Question

What is the answer to this question?

Answer 1

First, you would add 15/8 + 2/5 = 2 11/40
75/40 + 16/40 = 91/40
Simplify: 2 11/40
Next, you add 2 11/40 + (-7/8) = 1 2/5
2 11/40 - 7/8 = 2 + 11/40 - 7/8
LCD = 40
11/40  - 35/40 - 24/10
-24/10 = - 3/5
Simplify: 2 -3/5 = 1 2/5
Your final answer is 1 2/5
