Question

solve using property -3/2 x 5/7 - 3/2 x ( -9/14) + 2/7​

Answer 1

Answer:

$\frac{5}{28}$

Step-by-step explanation:

$sol {}^{n}$

$\frac{ - 3}{2} \times \frac{5}{7} - \frac{3}{2} \times ( \frac{ - 9}{4} ) + \frac{2}{7}$

$= ( \frac{ - 3}{2} ) \times ( \frac{5}{7} - \frac{9}{14} ) + \frac{2}{7}$

$= ( \frac{ - 3}{2} ) \times ( \frac{10 - 9}{14} ) + \frac{2}{7}$

$= ( \frac{ - 3}{2} ) \times \frac{1}{14} + \frac{2}{7}$

$= \frac{ - 3}{2} \times \frac{1}{14} + 4 \times \frac{1}{14}$

$= \frac{1}{14} ( \frac{ - 3}{2} + 4)$

$= \frac{1}{14} ( \frac{ - 3 + 8}{2} )$

$= \frac{1}{14} \times \frac{5}{2}$

$= \frac{5}{28}$
