Question

tìm x

x x 3/5 = 11/15 : 1/2

Answer 1

`x xx 3/5 = 11/15 : 1/2`

`=> x xx 3/5 = 11/15 xx 2`

`=> x xx 3/5 =22/15`

`=> x= 22/15 : 3/5`

`=> x = 22/15 xx 5/3`

`=>x= 22/9`

Answer 2

\(x\times\dfrac{3}{5}=\dfrac{11}{15}:\dfrac{1}{2}\)

\(x\times\dfrac{3}{5}=\dfrac{11}{15}\times\dfrac{2}{1}\)

\(x\times\dfrac{3}{5}=\dfrac{22}{15}\)

\(x=\dfrac{22}{15}:\dfrac{3}{5}\)

\(x=\dfrac{22}{15}\times\dfrac{5}{3}=\dfrac{22}{3}\times\dfrac{1}{3}\)

\(x=\dfrac{22}{9}\)
