Question

(2+2/3-1/4) ×1/5

7/15×15/14

Answer 1

\(\left(2+\frac{2}{3}-\frac{1}{4}\right)\cdot\frac{1}{5}\)

\(=\left(\frac{24}{12}+\frac{8}{12}-\frac{3}{12}\right)\cdot\frac{1}{5}\)

\(=\frac{29}{12}\cdot\frac{1}{5}\)

\(=\frac{29}{60}\)

\(\frac{7}{15}\cdot\frac{15}{14}=\frac{1}{1}\cdot\frac{1}{2}=\frac{1}{2}\) 

Answer 2

a) \(\left(2+\frac{2}{3}-\frac{1}{4}\right)\cdot\frac{1}{5}=\left(\frac{8}{3}-\frac{1}{4}\right)\cdot\frac{1}{5}=\frac{29}{12}\cdot\frac{1}{5}=\frac{29}{60}\)

b)\(\frac{7}{15}\cdot\frac{15}{14}=\frac{105}{210}=\frac{1}{2}\)
