C. 1/20
D. 3/16

Answer 1

-7/40 (None of the above)

Explanation:

Given problem,

→ (1/4) + (1/5) + ((-3/4) + (1/8))

Let's simplify the problem,

→ (1/4) + (1/5) + ((-3/4) + (1/8))

→ ((5/20) + (4/20)) + ((-6/8) + (1/8))

→ ((5 + 4)/20) + ((-6 + 1)/8)

→ (9/20) + (-5/8)

→ (18/40) + (-25/40)

→ (18 +(-25))/40

→ (18 - 25)/40

→ -7/40

Hence, the answer is -7/40.
