\(a\times5:6=25\)
\(a\times5=25\times6\)
\(a\times5=150\)
\(a=150:5\)
\(a=30\)
\(a\times5:6=25\\ a\times\dfrac{5}{6}=25\\ a=25:\dfrac{5}{6}\\ a=25\times\dfrac{6}{5}\\ a=30\)
a x 5 : 6 = 25
a x 5 = 25 x 6
a x 5 = 150
a =150 : 5
a = 30
\(a\times5:6=25\\ \Rightarrow a\times5=25\times6\\ \Rightarrow a\times5=150\\ \Rightarrow a=150:5\\ \Rightarrow a=30\)
