Question

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

Answer 1

Given: $3:1$
Total parts $=3+1=4$
So, Percentage of $3=\frac{3}{totalparts}\times 100$

$$\begin{gathered} =\frac{3}{4}\times 100 \\ =75\% \end{gathered}$$

Percentage of $1=\frac{1}{totalparts}\times 100$

$$\begin{gathered} =\frac{1}{4}\times 100 \\ =25\% \end{gathered}$$

Hence, percentage of each part of $3:1$is $75\%$ and $25\%$, respectively.
