Question

find 2/5×-3/7-1/14-3/7×3/5​

Answer 1

Answer:

2/5 × -3/7 - 1/4 - 3/7 × 3/5 = -19/28

Step-by-step explanation:

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

Taking LCM of denominators and re-writing the fractions with a common denominator:

= [ -6 × 4 - 1 × 35 - 9 × 4] / [ 35 × 4 ]

= [ -24 - 35 - 36] / [140]

= [ - 95 ] / 140

= -19 / 28
