What is 8 1/8 + 9 3/4?

17 7/8

Step-by-step explanation:

8 1/8 = 65/8

9 3/4 = 39/4 = 78/8

8 1/8 + 9 3/4

= 65/8 + 78/8

= (65 + 78) / 8

= 143/8

= (17*8 + 7) / 8

= (17*8) / 8 + 7/8

= 17 7/8

17 7/8

Step-by-step explanation:

First, we need to find the Least Common Denominator.

We know that 8 is evenly divisible by 4, so lets make the problem 8 1/8 + 9 6/8

We can add 6 to 1, which gets 7, or 7/8

We can add 8 to 9, which gets 17

So out final answer is 17 7/8
