Answer 2

Given: Ratio is 9:2:5

To find The inverse ratio of  9:2:5

Solution: For finding the inverse ratio of three numbers, first we have to find the L.C.M.(Least Common Multiple) of the given three numbers, then we have to multiply the L.CM. with 1/each given number as we have to find the inverse.

From above, we have

Ratio is 9:2:5

∴ L.C.M. of 9, 2, 5 is 90(9×2×5=90)

So the inverse ratio

=(1/9)×90:(1/2)×90:(1/5)×90

=10:45:18

Hence the inverse ratio of  9:2:5 is 10:45:18.
