1. Find Compounded ratio of `2:5,3:4`

Solution:
If `a:b` and `c:d` are two ratios, then `ac:bd` is called compounded ratio.


compounded ratio of `2:5,3:4` is `2 xx 3:5 xx 4=6:20=3:10`


2. Find Compounded ratio of `2:3,3:4,4:5`

Solution:
If `a:b` and `c:d` are two ratios, then `ac:bd` is called compounded ratio.


compounded ratio of `2:3,3:4,4:5` is `2 xx 3 xx 4:3 xx 4 xx 5=24:60=2:5`
