Question

ola. poderiam me explicar como resolvo isso:
(-2/3):(-5/6)1/5-2

Answer 1

$( \frac{-2}{3} ):( \frac{-5}{6} )* \frac{1}{5} -2 \\ \\ ( \frac{-2}{3} )*( \frac{-6}{5} )* \frac{1}{5} -2 \\ \\ \frac{12}{15} * \frac{1}{5} -2 \\ \\ \frac{12}{75} -2 \\ \\ \frac{12-150}{75} \\ \\ \frac{-138 ^{:3} }{75 ^{:3} } \\ \\ \frac{-46}{25}$

Espero ter ajudado! ^^
