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

	Kimberly	Winnie	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 Kimberly and Winnie shared the cost of their older brother's gift equally, the amount each paid for the gift is the same. 

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

Amount that Kimberly spent on the gift
= 8 u - 3 u
= 5 u

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

Answer(s): 62.5%
