\(\frac{22}{17}.\frac{34}{63}.\frac{21}{11}=\frac{11.2.17.2.21}{17.21.3.11}=\frac{2.2}{3}=\frac{4}{3}\)

Answer 2

\(\frac{22}{17}.\frac{34}{63}.\frac{21}{11}=\frac{11.2.17.2.21}{17.21.3.11}=\frac{2.2}{3}=\frac{4}{3}\)

Answer 3

\(\frac{22}{17}\cdot\frac{34}{63}\cdot\frac{21}{11}=\frac{22\cdot34\cdot21}{17\cdot63\cdot11}=\frac{2\cdot2\cdot1}{1\cdot3\cdot1}=\frac{4}{3}\)
