Question

Convert each part of the ratio to percentage: $3:1$.

Answer 1

Step 1: Find total parts by adding the given ratio.

Given ratio: $3:1$

$\therefore \mathrm{Total}\mathrm{parts}=3+1=4$

Step 2: Convert each part of the ratio to a percentage.

$\begin{array}{rcl}\mathrm{First}\mathrm{part}& =& \frac{3}{4}\\ & =& \left(\frac{3}{4}\right)\times 100\%\\ & =& 3\times 25\%\\ & =& 75\%\end{array}$

$\begin{array}{rcl}\mathrm{Second}\mathrm{part}& =& \frac{1}{4}\\ & =& \left(\frac{1}{4}\right)\times 100\%\\ & =& 1\times 25\%\\ & =& 25\%\end{array}$

Hence, the percentage of each part is $75\%\mathrm{and}25\%$ respectively.
