Kimberly and Jade folded paper cranes over two days. On Tuesday, Kimberly folded 17 paper cranes more than Jade. On Wednesday, Kimberly folded another 16 paper cranes and Jade folded another 1. At the end of the two days, Kimberly made ⁷₁₀ of the total number of cranes. What was the number of paper cranes that Jade folded?

	Kimberly	Jade	Difference
Before	1 u + 17	1 u	17
Change	+ 16	+ 1
After	1 u + 33	1 u + 1	32
Comparing between Kimberly and Jade in the end	7 p	3 p	4 p

Difference between the number of paper cranes that Kimberly and Jade folded in the end is repeated.

Difference between the number of paper cranes that Kimberly and Jade folded in the end
= 7 p - 3 p
= 4 p

Difference between the number of paper cranes that Kimberly and Jade folded in the end
= (1 u + 33) - (1 u + 1)
= 1 u + 33 - 1 u - 1
= 33 - 1
= 32

4 p = 32

1 p = 32 ÷ 4 = 8

Number of paper cranes that Jade folded
= 3 p
= 3 x 8
= 24

Answer(s): 24
