first expand
-3/2 + 9/4 + 1/8
as you can see all of them are factors of two so we can change them to a common denominator.
-3*4/2*4 +9*2/8 +1/8
18/8+1/8 -12/8 Now add all the numerators
The answer is 7/8

7/8
-3/2 + 9/4 - (-1/8)
= -12/8 + 18/8 + 1/8
= (-12+18+1)/8
= 7/8
which also equals 0.875

You need to learn how to do these on your own. Can't take yahoo answers to school with you for your tests.
