\(\frac{-3}{4}:\left(\frac{2}{15}\cdot x\right)=3:\frac{2}{5}=\frac{15}{2}\)
\(\frac{2}{15}\cdot x=\frac{3}{4}:\frac{15}{2}=\frac{1}{10}\)
\(x=\frac{1}{10}:\frac{2}{15}=\frac{3}{4}\)
=>\(x=\frac{3}{4}\)
tk mik nha bạn
-3/4:(2/15*x)= 15/2
2/15*x= -3/4 :15/2 = -1/10
x= -1/10 :2/15 = -3/4
Vậy x = -3/4
