Answer 1

the answer is 3/8

Explanation:

Answer 2

3/8

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
