Answer 2

Answer:

( * means multiplication )

when a divisions numerator and denomineter is negative it becomes positive

Step-by-step

(-7/8 * 15/-7) - (1*1/4) + (1/2 + 1/4)

(-105/-56) - (4/1) + (1/8)

105/56 - 4/1 + 1/8

105/56 - (56/8 + 1/8) = 105 / 56 - 57 / 8

105/56- 399/56 = -294/56

(only if simplification needed)

-147/28 = -21/4 = $5 \frac{1}{4}$
