Question

8/15 : 2/11 - 7/15 : 2/11

Answer 1

\(\dfrac{8}{15}:\dfrac{2}{11}-\dfrac{7}{15}:\dfrac{2}{11}\)

\(=\left(\dfrac{8}{15}-\dfrac{7}{15}\right).\dfrac{11}{2}\)

\(=\dfrac{1}{15}.\dfrac{11}{2}=\dfrac{11}{30}\)

Answer 2

\(=\left(\dfrac{8}{15}-\dfrac{7}{15}\right):\dfrac{2}{11}\\ =\dfrac{1\times11}{15\times2}=\dfrac{11}{30}\)

Answer 3

\(\left(\dfrac{8}{15}-\dfrac{7}{15}\right):\dfrac{11}{2}\)

\(\dfrac{1}{15}x\dfrac{11}{2}=\dfrac{11}{30}\)
