Let us assume the common ratio = x
Then
3x + 2x = 32
5x = 32
x = 32/5
= 6.4
Then the ratio of 3:2 for the number 32 can be written as = 3 * 6.4:2 * 6.4
= 19.2:12.8
So the number 32 when divided in the ratio of 3:2 will be 19.2:12.8. I hope the procedure is absolutely clear to you. By using this procedure you can always solve problems of similar nature without taking any outside help. Only be careful during the calculation part.
