Answer 5

a) \(\frac{15}{18}\)= \(\frac{15:3}{18:3}\)= \(\frac{5}{6}\).

b) \(\frac{144}{351}\)= \(\frac{144:9}{351:9}\)= \(\frac{16}{39}\).

c) \(\frac{6}{30}\)= \(\frac{6:6}{30:6}\)= \(\frac{1}{5}\).

d) \(\frac{2005}{3000}\)= \(\frac{2005:5}{3000:5}\)= \(\frac{401}{600}\).

Answer 6

\(\frac{15}{18}=\frac{15:3}{18:3}=\frac{5}{6}\)

\(\frac{144}{351}=\frac{144:9}{351:9}=\frac{16}{39}\)

\(\frac{6}{30}=\frac{6:6}{30:6}=\frac{1}{5}\)

\(\frac{2005}{3000}=\frac{2005:5}{3000:5}=\frac{401}{600}\)
