Question

what is 1/5 × -3/2 +4/5 × -2/7 × -1/6 × -2/7

Answer 1

Answer:

$\frac{-457}{1470}$

Step-by-step explanation:

$\frac{1}{5} \times \frac{-3}{2} + \frac{4}{5} \times \frac{-2}{7} \times \frac{-1}{6} \times \frac{-2}{7}$

$(\frac{1}{5} \times \frac{-3}{2}) + (\frac{4}{5} \times \frac{-2}{7} \times \frac{-1}{6} \times \frac{-2}{7})$

$\frac{-3}{10} +\frac{-16}{1470}$

$=\frac{-457}{1470}$

Answer 2

Answer: 4/1225

Step-by-step explanation:

1/5 × -3/2 +4/5 × -2/7 × -1/6 × -2/7

Multiplying an even number of negative terms makes the product positive:

= 1/5 * 4/5 * 1/7 * 1/2 * 1/7

= 1/5 * 4/5 * 1/7 * 1/7

= 4/1225
