Question

Làm phép tính :

a ) \(\frac{5}{6}:\frac{-7}{12}\) 

b ) -7 : \(\frac{14}{3}\)

Answer 1

a,  \(\frac{5}{6}:\frac{-7}{12}=\frac{5}{6}.\frac{-12}{7}=-\frac{10}{7}\)

 

b, -7 :\(\frac{14}{3}=-7.\frac{3}{14}=-\frac{3}{2}\)

Answer 2

\(\frac{5}{6}:\frac{-7}{12}=\frac{5}{6}.\frac{-12}{7}=5.\frac{-2}{7}=\frac{10}{7}\)

\(-7:\frac{14}{3}=-7.\frac{3}{14}=-1.\frac{3}{2}=\frac{-3}{2}\)
