Answer 1

\(\dfrac{6}{9}\) = \(\dfrac{6:3}{9:3}\) = \(\dfrac{2}{3}\)                    \(\dfrac{24}{36}\) = \(\dfrac{24:12}{36:12}\) = \(\dfrac{2}{3}\)

\(\dfrac{80}{240}\) = \(\dfrac{80:80}{240:80}\) = \(\dfrac{1}{3}\)           \(\dfrac{75}{100}\) = \(\dfrac{75:25}{100:25}\) = \(\dfrac{3}{4}\)

\(\dfrac{123123}{103103}\) = \(\dfrac{123123:1001}{103013:1001}\) = \(\dfrac{123}{103}\)

\(\dfrac{2121}{3232}\) = \(\dfrac{2121:101}{3232:101}\) = \(\dfrac{21}{32}\)
