Question

4) Circle all the ratios that are are equivalent to each other. 4:7 8:15 16:28 2:3 20:35

Answer 1

To find the equivalent ratios, we must simplify the fractions when it is possible:

$\begin{gathered} \frac{16}{28}=\frac{\frac{16}{4}}{\frac{28}{4}}=\frac{4}{7} \\ \frac{20}{35}=\frac{\frac{20}{5}}{\frac{35}{5}}=\frac{4}{7} \end{gathered}$

Therefore, the equivalent ratios are 4:7, 16:28 and 20:35
