Jean's and Olivia's savings were in the ratio of 4 : 9. Both of them shared the cost of their father's present equally. Jean's remaining savings was ¹₄ as much as Olivia's savings. What percentage of her savings did Jean spend? Correct the answer to 1 decimal place.

	Jean	Olivia	Difference
Before	4x3 = 12 u	9x3 = 27 u	5x3 = 15 u
Change	- 7 u	- 7 u
After	1x5 = 5 u	4x5 = 20 u	3x5 = 15 u

Since Jean and Olivia shared the cost of their father's present equally, the amount each paid for the present is the same. 

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

Amount that Jean spent on the present
= 12 u - 5 u
= 7 u

Percentage of her savings that Jean spent
= ⁷₁₂ x 100%
≈ 58.3%

Answer(s): 58.3%
