Adding and Subtracting Fractions with Unlike Denominators

When adding and subtracting fractions you must first find a ______ ___________.

Hello, Math Genius! We have a fun math problem for you. Can you solve this equation for us? $$\frac{5}{6}-\frac{2}{3}$$ Remember, the key is to simplify your answer! Here's a hint: When you subtract fractions, make sure the denominators (the bottom numbers) are the same. If they're not, you might need to find a common denominator first.

Let's play a fun game! Can you figure out how to make $$\frac{3}{4}$$ using only unit fractions? A unit fraction is a fraction where the numerator (the top number) is 1. So, $$\frac{1}{4}$$ , $$\frac{1}{2}$$ , and $$\frac{1}{3}$$ are all unit fractions.

$$\frac{2}{4}+\frac{3}{8}$$ Let's play a fun game! Can you solve this simple math problem and simplify your answer? I believe in you, you can do it!

Here's a hint: When you add fractions, make sure the bottom numbers (the denominators) are the same. If they are not, find a common denominator and convert the fractions before adding them.

Also, remember to simplify your answer to its lowest terms.

Imagine you're at a party where everyone is eating pizza. There's only one pizza left. If we cut the pizza like this, can you tell me what fraction it represents? Let's think of the whole pizza as 1. So, is it 1, 2/3, 3/4 or 1/4 of the pizza?

Let's pretend you're a math magician and your magic wand can solve math problems! Let's try it on this one: $$\frac{4}{6}-\frac{1}{2}$$ . Make sure to make your answer as simple as possible!

$$\frac{1}{2}+\frac{1}{6}$$ Hey there! We have a fun math problem here. Can you tell us the first step to solve this equation? Don't worry, take your time.

$$\frac{9}{15}-\frac{2}{5}$$ Let's have some fun with numbers! Can you solve this equation and simplify your answer? Don't worry, take your time and do your best!

Here's a hint: When you subtract fractions, make sure the denominators (the bottom numbers) are the same. Then, just subtract the numerators (the top numbers). Don't forget to simplify your answer!

Let's imagine this: Sally has a yummy, chocolate chip cookie. She eats some of it during her lunch break, and she only has $$\frac{1}{2}$$ (half) of her cookie left. On the other side, Billium, who was eating his oatmeal raisin cookie, has $$\frac{1}{4}$$ (a quarter) of his cookie left from his lunch.

Now, let's think about this fun question: If Sally and Billium decided to put their leftover cookies together, how much of a cookie would they have in total? Here's a hint: when we add fractions, we add the top numbers (the numerators) and keep the bottom number (the denominator) the same.

Once you have a common denominator you can combine the (a)
