Answer 2

f) \(\dfrac{3}{4}\cdot x=\dfrac{3}{5}\)

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

        \(x=\dfrac{4}{5}\)

g) \(x+\dfrac{1}{2}=\dfrac{3}{8}\cdot\dfrac{4}{3}\)

   \(x+\dfrac{1}{2}=\dfrac{1}{2}\)

   \(x=\dfrac{1}{2}-\dfrac{1}{2}\)

   \(=0\)

Answer 3

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

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

\(x=\dfrac{12}{15}\)

\(x=\dfrac{4}{5}\)

g)\(x+\dfrac{1}{2}=\dfrac{12}{24}\)

\(x+\dfrac{1}{2}=\dfrac{1}{2}\)

\(x=\dfrac{1}{2}-\dfrac{1}{2}\)

\(x=0\)
