Question

Add. Write your answer in simplest form. 3/5 + 5/8

Answer 1

3/5 + 5/8 = ?

Since they both have different denominators (bottom numbers), then we must find the GCD (greatest common denominator).

What can be divided into 5 AND 8? 40!

How many times can 40 be divided into 5? 8 times!

How many times can 40 be divided into 8? 5 times!

So, you take that number and multiply it by the numerator (top number) and you get your new yet equivalent fraction.

3/5 turns into 24/40 & 5/8 turns into 25/40

So, our new question looks like this :

24/40 + 25/40

Since both of these fractions have the same denominator (bottom number), you can simply add the top numbers together! :)

24 + 25 = 49

So, our answer to 3/5 + 5/8 = 49/40

Turn this into a mixed number.

49/40 = 1 9/40

So, your FINAL ANSWER is 1 9/40
