Question

\(x\) : \(\dfrac{1}{2}\) = \(\dfrac{3}{4}\) x \(\dfrac{4}{5}\) 

X x \(\dfrac{1}{3}\) = 1 - \(\dfrac{3}{4}\) 

 

 

Answer 1

\(a,x:\dfrac{1}{2}=\dfrac{3}{5}\\ x=\dfrac{3}{5}\times\dfrac{1}{2}\\ x=\dfrac{3}{10}\\ ----------\\ b,x\times\dfrac{1}{3}=\dfrac{4-3}{4}\\ x\times\dfrac{1}{3}=\dfrac{1}{4}\\ x=\dfrac{1}{4}:\dfrac{1}{3}\\ x=\dfrac{1}{4}\times\dfrac{3}{1}\\ x=\dfrac{3}{4}\)

Answer 2

\(x\div\dfrac{1}{2}=\dfrac{3}{4}\times\dfrac{4}{5}\)

\(x\div\dfrac{1}{2}=\dfrac{3}{5}\)

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

\(x=\dfrac{3\times1}{5\times2}\)

\(x=\dfrac{3}{10}\)

 

 

\(x\times\dfrac{1}{3}=1-\dfrac{3}{4}\)

\(x\times\dfrac{1}{3}=\dfrac{1}{4}\)

\(x=\dfrac{1}{3}\div\dfrac{1}{4}\)

\(x=\dfrac{1}{3}\times\dfrac{4}{1}\)

\(x=\dfrac{4}{3}\)
