Question

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

Answer 1

Step-by-step explanation:

=3/5+5/8=24+25/40

=49/40=1.225

Answer 2

$\dfrac{3}{5}$ + $\dfrac{5}{8}$ = ?

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.

$\dfrac{3}{5}$ turns into $\dfrac{24}{40}$ & $\dfrac{5}{8}$ turns into $\dfrac{25}{40}$;

So, our new question looks like this :

$\dfrac{24}{40}$ + $\dfrac{25}{40}$

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

24 + 25 = 49

So, our answer to $\dfrac{3}{5}$ + $\dfrac{5}{8}$ = $\dfrac{49}{40}$

Turn this into a mixed number.

$\dfrac{49}{40}$ = $1 \dfrac{9}{40}$

So, your FINAL ANSWER is $1 \dfrac{9}{40}$
