Question

Write two ratios equivalent to 10 : 12.

Answer 1

First, divide the ratio by 2:

`10\colon12\rightarrow(10)/(2)\colon(12)/(2)\rightarrow5\colon6`

Now, multiply it by two to get the second ratio:

`10\colon12\rightarrow10\cdot2\colon12\cdot2\rightarrow20\colon24`

Thereby, the two ther ratios would be

`\begin{gathered} 5\colon6 \\ \text{and} \\ 20\colon24 \end{gathered}`
