    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
