Lynn's and Hazel's savings were in the ratio of 4 : 7. Both of them shared the cost of their older sister's present equally. Lynn's remaining savings was ¹₃ as much as Hazel's savings. What percentage of her savings did Lynn spend? Correct the answer to 1 decimal place.

	Lynn	Hazel	Difference
Before	4x2 = 8 u	7x2 = 14 u	3x2 = 6 u
Change	- 5 u	- 5 u
After	1x3 = 3 u	3x3 = 9 u	2x3 = 6 u

Since Lynn and Hazel shared the cost of their older sister's present equally, the amount each paid for the present is the same. 

So, the difference in the amounts between Lynn and Hazel at first and in the end remains the same.  Make the difference in the amounts between Lynn and Hazel at first and in the end the same. LCM of 3 and 2 is 6.

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

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

Answer(s): 62.5%
