Find the ratio of:-
$3 y e a r s$ to $8 m o n t h s$

Open in App

Solution

Given
$3 y e a r s$ to $8 m o n t h s$
we know that,
$\begin{array}{rcl} 1 y e a r & = & 12 m o n t h s \\ \Rightarrow & 3 y e a r s = (3 \times 12) m o n t h s \\ = & 36 m o n t h s \end{array}$
so, $36 m o n t h s$ to $8 m o n t h s = 36 : 8$
$= 9 : 2$
Hence, $9 : 2$ is the required ratio.
