Answer 3

\(\dfrac{1}{2}\times\left(\dfrac{1}{3}-\dfrac{1}{5}\right)=\dfrac{1}{2}\times\left(\dfrac{5}{15}-\dfrac{3}{15}\right)=\dfrac{1}{2}\times\dfrac{2}{15}=\dfrac{1}{15}\)

Answer 4

\(\dfrac{1}{3}\times\dfrac{1}{2}-\dfrac{1}{5}\times\dfrac{1}{2}\)

\(=\dfrac{1}{6}-\dfrac{1}{10}\)

\(=\dfrac{1}{15}\)

Answer 5

1/6 - 1/10 = 4/60 = 1/15
