First you would start getting the denominators to the same number and you could do this by multiplying 9/10 by 4, and 7/8 by 5 to get the denominators to 40 and when you add the fractions you get 71/40 so the answer would be D. About 2

Hey there James!

Your answer: 71/40 = 1.77500 which is about 2.

We simplify 7/8

9/10 + 7/8

We find that the least common multiple is 40.

So we do, [tex] \frac{9*4+7*5}{40} = 71/40[/tex]

Your answer is about 2.
