Question

Find using property (2/7) x (-5/4) + (13/4) x (2/7)

Answer 1

Answer:

$= \frac{4}{7}$

Step-by-step explanation:

$sol {}^{n}$

$( \frac{2}{7}) \times ( \frac{ - 5}{4}) + ( \frac{13}{4}) \times ( \frac{2}{7} )$

$= \frac{2}{7} ( \frac{ - 5}{4} + \frac{13}{4} ) \: (distributive \: prop)$

$= \frac{2}{7}( \frac{ - 5 + 13}{4} )$

$= \frac{2}{7} \times ( \frac{8}{4})$

$= \frac{2}{7} \times \frac{8}{4}$

$= \frac{4}{7}$
