Answer:

3/8

Step-by-step explanation:

We want to evaluate

b - (-1/8) + c

where   b = 2 and   c = -7/4

First, replace b and c values into the expression

2 - (-1/8) + (-7/4)

Then, eliminate the parenthesis

2 + 1/8 - 7/4

Finally, express all terms as fractions with the same denominator, and perform the addition and subtraction

2*8/8 + 1/8 - 7/4 * 2/2

16/8 + 1/8 - 14/8

(16 + 1 - 14)/8

3/8

Answer:

the answer is 3/8
