Question

Resolva a espressão (5/8+5/4+5/2)-(-8/5)

Answer 1

Oie, Td Bom?!

$= ( \frac{5}{8} + \frac{5}{4} + \frac{5}{2} ) - ( - \frac{8}{5} )$

$= ( \frac{5 + 10 + 20}{8} ) - ( - \frac{8}{5} )$

$= \frac{35}{8} - ( - \frac{8}{5} )$

$= \frac{35}{8} + \frac{8}{5}$

$= \frac{175 + 64}{40}$

$= \frac{239}{40}$
