Jade and Erika folded paper cranes over two days. On Monday, Jade folded 49 paper cranes more than Erika. On Tuesday, Jade folded another 14 paper cranes and Erika folded another 19. At the end of the two days, Jade made ⁷₁₀ of the total number of cranes. What was the number of paper cranes that Jade folded?

	Jade	Erika	Difference
Before	1 u + 49	1 u	49
Change	+ 14	+ 19
After	1 u + 63	1 u + 19	44
Comparing between Jade and Erika in the end	7 p	3 p	4 p

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

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

Difference between the number of paper cranes that Jade and Erika folded in the end
= (1 u + 63) - (1 u + 19)
= 1 u + 63 - 1 u - 19
= 63 - 19
= 44

4 p = 44

1 p = 44 ÷ 4 = 11

Number of paper cranes that Jade folded
= 7 p
= 7 x 11
= 77

Answer(s): 77
