Question

Using property find: 2/5*(-3/7) -1/6*3/2+1/14*3/5​

Answer 1

Answer:

-53/140

Step-by-step explanation:

$= > (\frac{2}{5}) ( \frac{ - 3}{7} ) - ( \frac{1}{6} )( \frac{3}{2} ) + ( \frac{1}{14} )( \frac{3}{5} ) \\ \\ = - \frac{6}{35} - \frac{1}{4} + \frac{3}{70} \\ \\ = \frac{ (- 6 \times 4) + ( - 1 \times 35) + (3 \times 2)}{140} \\ \\ = \frac{ - 24 - 35 + 6}{140} \\ \\ = \frac{ - 53}{140}$
