Here's how to add

7
8
+
5
8

Step 1

Since our denominators match, we can add the numerators.

7 + 5 = 12

Now we have an answer.

12
8

Step 2

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

12
8
÷ 2 =
6
4

Now, try the same number again.

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

6
4
÷ 2 =
3
2

Now, try the same number again.

Nope. Try the next prime number, 3...

No good. 3 is larger than 2. So we're done reducing.

Congratulations! Here's your final answer to 7/8 + 5/8
