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} (16)/(28)=((16)/(4))/((28)/(4))=(4)/(7) \\ (20)/(35)=((20)/(5))/((35)/(5))=(4)/(7) \end{gathered}`

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