Sarah's and Victoria's savings were in the ratio of 4 : 9. Both of them shared the cost of their older brother's present equally. Sarah's remaining savings was ²₅ as much as Victoria's savings. What percentage of her savings did Victoria spend? Correct the answer to 1 decimal place.

	Sarah	Victoria	Difference
Before	4x3 = 12 u	9x3 = 27 u	5x3 = 15 u
Change	- 2 u	- 2 u
After	2x5 = 10 u	5x5 = 25 u	3x5 = 15 u

Since Sarah and Victoria shared the cost of their older brother's present equally, the amount each paid for the present is the same. 

So, the difference in the amounts between Sarah and Victoria at first and in the end remains the same.  Make the difference in the amounts between Sarah and Victoria at first and in the end the same. LCM of 5 and 3 is 15.

Amount that Victoria spent on the present
= 27 u - 25 u
= 2 u

Percentage of her savings that Victoria spent
= ²₂₇ x 100%
≈ 7.4%

Answer(s): 7.4%
