Vanessa's and Roshel's savings were in the ratio of 2 : 5. Both of them shared the cost of their uncle's present equally. Vanessa's remaining savings was ¹₅ as much as Roshel's savings. What percentage of her savings did Vanessa spend? Correct the answer to 1 decimal place.

	Vanessa	Roshel	Difference
Before	2x4 = 8 u	5x4 = 20 u	3x4 = 12 u
Change	- 5 u	- 5 u
After	1x3 = 3 u	5x3 = 15 u	4x3 = 12 u

Since Vanessa and Roshel shared the cost of their uncle's present equally, the amount each paid for the present is the same. 

So, the difference in the amounts between Vanessa and Roshel at first and in the end remains the same.  Make the difference in the amounts between Vanessa and Roshel at first and in the end the same. LCM of 3 and 4 is 12.

Amount that Vanessa spent on the present
= 8 u - 3 u
= 5 u

Percentage of her savings that Vanessa spent
= ⁵₈ x 100%
≈ 62.5%

Answer(s): 62.5%
