Question

(- 5/6) : (- 7/8) = ?

Answer 1

Oii!

$( - \frac{5}{6} ) \div ( - \frac{7}{8} ) =$

$\frac{5}{6} \times \frac{8}{7}$

$\frac{5}{3} \times \frac{4}{7}$

$\frac{20}{21}$

>>> 20/21

Answer 2

Oie, Td Bom?!

= (- 5/6) ÷ (- 7/8)

= 5/6 ÷ 7/8

= 5/6 . 8/7 ⇐ Simplifica por 2.

= 5/3 . 4/7

= [5 . 4]/[7 . 3]

= 20/21
