Question

(1/2×-3/4)-(3/8×-1/4)+(-3/5×-1/4)

Answer 1

Answer:

$\frac{ - 33}{160}$

Step-by-step explanation:

$( \frac{1}{2} \times \frac{ - 3}{4} ) - ( \frac{3}{8} \times \frac{ - 1}{4} ) + ( \frac{ - 3}{5} \times \frac{ - 1}{4} ) \\ = (\frac{ - 3}{8} ) - ( \frac{ - 3}{32} ) + ( \frac{3}{20} ) \\ = \frac{ - 3}{8} + \frac{3}{32} + \frac{3}{20} \\ = \frac{ - 60 + 15 + 12}{160} \\ = \frac{ - 33}{160}$
