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
