Answer 2

a) 4/6:6/5=5/9

b) 3/8x6/5=9/20

Answer 3

a) 5/9

b) 9/20

Answer 4

\(\frac{1}{2}\times\frac{4}{3}\div\frac{6}{5}\)

\(=\frac{1}{2}\times\frac{4}{3}\times\frac{5}{6}\)

\(=\frac{1\times4\times5}{2\times3\times6}\)

\(=\frac{5}{9}\)

b,\(\frac{1}{2}\div\frac{4}{3}\times\frac{6}{5}\)

\(=\frac{1}{2}\times\frac{3}{4}\times\frac{6}{5}\)

\(=\frac{1\times3\times6}{2\times4\times5}\)

\(=\frac{9}{20}\)
