Solution

Step-1: Find $F a t h e r' s a g e : M o t h e r' s a g e$
$F a t h e r' s a g e : M o t h e r' s a g e$ $=$ $45 : 40$
Step-2: Simplify the ratio $45 : 40$
$45 : 40$ $=$ $\frac{45 \div 5}{40 \div 5}$ ( To simplify $45 : 40$ divide it by HCF of $45$ and $40$ The HCF of $45$ and $40$ is $5$ )
$45 : 40$ $=$ $\frac{9}{8}$ $=$ $9 : 8$
Hence, the ratio $F a t h e r' s a g e : M o t h e r' s a g e$ is $9 : 8$
