Question

simplify using appropriate property( pls pls pls pls pls pls pls help me pls tomorrow is my exam pls)​

Answer 1

Step-by-step explanation:

it is done by distributive properties

a (b+c) = ab + ac

$\frac{5}{3} ( \frac{ - 3}{2} - \frac{6}{2}) + \frac{2}{5}$

$= \frac{5}{3}( \frac{ - 3 - 6}{2}) + \frac{2}{5}$

$= \frac{5}{3}( \frac{ - 9}{2})+ \frac{2}{5} \\ = \frac{ - 45}{6} + \frac{2}{5} \\= \frac{(-45 \times 5) + (2 \times 6)}{30} \\= \frac{ - 225 + 12}{30} \\= \frac{ - 213}{30} \\= 7.1$
