The number that needs to be split as per the question = 2.50
The ratio in which the number needs to be split = 3:2
Let us assume the common ratio to be = x
Then
3x + 2x = 2.50
5x = 2.50
x = 2.50/5
= 0.50
Then
The ratio in which the number 2.50 can be divided = 3 * 0.5: 2 * 0.5
= 1.5:1
So from the above deduction, we can conclude that the number 25 can be split in the ratio 1.5:1.
