Welcome, young mathematicians! Today’s lesson is all about adding fractions with like denominators. We will explore how to combine these tasty fractional treats into something even sweeter!
Imagine you’re at a pizza party with your friends. Each pizza is sliced into equal pieces, and you are all super excited to eat! 🥳
Let’s say we have two types of pizzas:
But wait! You’ve taken some slices from each pizza.
Now, you want to find out how many slices you both have eaten together. How can we figure that out using fractions? 🤔
For Pizza A, you have eaten of 2 out of 4 slices, which we write as:
[ \frac{2}{4} ]
For Pizza B, your friend has eaten 1 out of 4 slices, represented as:
[ \frac{1}{4} ]
Since both pizzas have the same number of slices (the denominator is the same), we can add the fractions easily!
To find the total slices eaten, we add the numerators together. Here’s how we write it:
[ \frac{2}{4} + \frac{1}{4} = \frac{2 + 1}{4} ]
Now, let’s complete the addition:
[ \frac{2 + 1}{4} = \frac{3}{4} ]
So, you and your friend have eaten a total of 3 out of 4 slices together! 🍕🎉
Isn’t that fun? By using fractions, we can easily combine what you and your friend enjoyed at the pizza party. Today, we will practice more examples like this one, where we can add fractions with like denominators to discover how many delicious slices or pieces we have collected!
