Fraction Representation Of Election Votes: A Math Problem
Hey guys! Let's dive into a fun math problem involving fractions and election results. Imagine a class of 2nd ESO students holding elections to choose their class delegate. We have four candidates: MarĂa, Julia, Ălex, and Carlos, each receiving a certain number of votes. Our mission is to represent the votes each candidate received as a fraction of the total votes cast. This is a super practical way to see how math can help us understand real-world situations, like elections! So, grab your thinking caps, and let's get started!
Understanding the Problem: Votes and Fractions
Okay, first things first, let's break down the problem. We know that votes were cast, and each candidate got a share of those votes. To represent these shares as fractions, we need to remember what a fraction actually is. A fraction is just a way of showing a part of a whole. The denominator (the bottom number) tells us the total number of parts, and the numerator (the top number) tells us how many of those parts we're interested in. In this case, the 'whole' is the total number of votes, and the 'parts' are the votes each candidate received.
To find the fraction for each candidate, we'll need to do a couple of things. First, we need to figure out the total number of votes. This is pretty easy â we just add up the votes for each candidate. Then, to get the fraction for a specific candidate, we'll put their votes as the numerator and the total votes as the denominator. For example, if a candidate got 10 votes, and there were 50 total votes, the fraction representing their votes would be 10/50. We can often simplify these fractions, which we'll talk about later. This makes the numbers smaller and easier to understand, while still showing the same proportion. It's like cutting a pizza into 8 slices instead of 16 â you still have the same amount of pizza if you eat 4 slices in either case.
Why is this important? Representing votes as fractions helps us quickly compare the results. We can see at a glance who got the largest share of the votes, and by what proportion. This is super useful in all sorts of situations, not just elections. Think about dividing a cake, sharing resources, or even understanding data in science or economics. Fractions are everywhere, and understanding them is a key skill!
Calculating the Total Votes
Before we can express each candidate's votes as a fraction, we need to determine the total number of votes cast in the election. This is a crucial first step because the total number of votes will serve as the denominator in our fractions. To find this, we simply add up the votes received by each candidate. The problem states that:
- MarĂa received 14 votes.
 - Julia received 6 votes.
 - Ălex received 8 votes.
 - Carlos received 2 votes.
 
So, let's add these up: 14 + 6 + 8 + 2 = 30 votes. Therefore, there were a total of 30 votes cast in the election. This number, 30, is going to be the denominator for all our fractions. Remember, the denominator represents the whole, and in this case, the whole is the entire pool of votes cast. Knowing the total allows us to accurately represent each candidate's share of the votes as a fraction of this whole.
Now that we know the total number of votes, we are one step closer to representing each candidate's performance in a fractional form. Weâve essentially found the base upon which we will build our fractions. Think of it like this: if we were building a cake, finding the total votes is like preparing the cake pan - itâs necessary before we can add any ingredients (in this case, the individual votes). So, with the total votes figured out, we're ready to move on to the exciting part: calculating the individual fractions for each candidate. Let's get to it!
Expressing Each Candidate's Votes as a Fraction
Alright, now for the exciting part! Weâre going to take the votes each candidate received and express them as fractions of the total votes. Remember, we figured out that the total number of votes is 30, so that's going to be the denominator for all our fractions. Let's go through each candidate one by one.
- MarĂa: MarĂa received 14 votes. So, the fraction representing MarĂa's votes is 14/30. This means that out of the total 30 votes, MarĂa received 14 of them.
 - Julia: Julia received 6 votes. The fraction for Julia's votes is 6/30. This shows that Julia got 6 out of the 30 votes cast.
 - Ălex: Ălex received 8 votes. Therefore, the fraction representing Ălex's votes is 8/30. This means Ălex got 8 out of the total 30 votes.
 - Carlos: Carlos received 2 votes. The fraction for Carlos's votes is 2/30. This indicates that Carlos received 2 out of the 30 votes cast.
 
So, there you have it! We've successfully represented each candidate's votes as a fraction. But, we're not quite done yet. These fractions can be simplified, making them easier to understand and compare. Think of it like this: 14/30 might sound like a complicated number, but what if we could find a way to express it in simpler terms? That's where simplifying fractions comes in. It's like translating a long sentence into a shorter, punchier one â it still means the same thing, but it's easier to grasp. Letâs move on to simplifying these fractions and making our results even clearer.
Simplifying the Fractions
Okay, guys, let's talk about simplifying fractions. Simplifying a fraction means reducing it to its simplest form, where the numerator and the denominator have no common factors other than 1. This doesn't change the value of the fraction; it just makes it easier to understand and work with. To simplify, we need to find the greatest common divisor (GCD) of the numerator and the denominator and then divide both by that GCD.
Let's take each of our fractions and see if we can simplify them:
- MarĂa (14/30): The GCD of 14 and 30 is 2. Dividing both the numerator and the denominator by 2, we get 7/15. So, MarĂa's votes, in simplest form, are 7/15.
 - Julia (6/30): The GCD of 6 and 30 is 6. Dividing both by 6, we get 1/5. Julia's votes, simplified, are 1/5. This means Julia received one-fifth of the total votes.
 - Ălex (8/30): The GCD of 8 and 30 is 2. Dividing both by 2, we get 4/15. So, Ălex's votes in simplest form are 4/15.
 - Carlos (2/30): The GCD of 2 and 30 is 2. Dividing both by 2, we get 1/15. Carlos's votes, simplified, are 1/15.
 
Now, we have all the votes represented as simplified fractions: 7/15, 1/5, 4/15, and 1/15. These simplified fractions give us a clearer picture of the proportion of votes each candidate received. For instance, we can easily see that MarĂa got 7 out of every 15 votes, while Carlos only got 1 out of every 15. Simplifying fractions is a super useful skill, not just for this problem, but for many mathematical and real-life situations. It helps us to see the core relationships between numbers, without getting bogged down in unnecessary complexity. Great job, guys! We're almost at the finish line.
Interpreting the Results
Alright, let's put on our detective hats and interpret what these fractions actually mean in the context of the election! We've done the math, simplified the fractions, and now it's time to understand the story they tell. We have the following simplified fractions representing each candidate's votes:
- MarĂa: 7/15
 - Julia: 1/5
 - Ălex: 4/15
 - Carlos: 1/15
 
Looking at these fractions, we can immediately see some key takeaways. The candidate with the largest fraction received the most votes, and in this case, that's MarĂa with 7/15 of the votes. This means MarĂa won the election and will be the class delegate! Great job, MarĂa! We can also compare the fractions to understand the relative performance of the other candidates. For example, Ălex received 4/15 of the votes, which is more than Julia's 1/5 and Carlos's 1/15. This tells us that Ălex came in second place in the election.
To make these comparisons even clearer, it can be helpful to think about what these fractions mean in terms of percentages. While we haven't explicitly calculated percentages, we can get a rough idea. For instance, 7/15 is a little less than half (which would be 7.5/15), so MarĂa received a little less than 50% of the votes. Similarly, 1/5 is equal to 20%, and 1/15 is a smaller percentage. This gives us a more intuitive sense of the distribution of votes. Interpreting the results is a crucial step in any mathematical problem. It's not enough just to crunch the numbers; we need to understand what those numbers mean in the real world. In this case, we've successfully used fractions to analyze election results and determine the winner! Awesome work, everyone!
Conclusion
So, guys, we've successfully navigated this problem of representing election votes as fractions! We started with raw vote counts, calculated the total votes, expressed each candidate's votes as a fraction, simplified those fractions, and finally, interpreted the results.
