Question

\(7:\frac{1}{5}=\)

\(\frac{5}{12}-\frac{5}{15}=\)

\(\frac{7}{9}:\frac{5}{12}=\)

Answer 1

\(7:\frac{1}{5}=7\cdot\frac{5}{1}=35\)

\(\frac{5}{12}-\frac{5}{15}=\frac{5\cdot15-5\cdot12}{12\cdot15}=\frac{1}{12}\)

\(\frac{7}{9}:\frac{5}{12}=\frac{7}{9}\cdot\frac{12}{5}=\frac{28}{15}\)

Answer 2

\(7:\frac{1}{5}=35\)

\(\frac{5}{12}-\frac{5}{15}=\frac{1}{12}\)

\(\frac{7}{9}:\frac{5}{12}=1\frac{13}{15}=\frac{28}{15}\)
