Xylia and Gabby folded paper cranes over two days. On Thursday, Xylia folded 20 paper cranes more than Gabby. On Friday, Xylia folded another 39 paper cranes and Gabby folded another 29. At the end of the two days, Xylia made ⁵₈ of the total number of cranes. What was the number of paper cranes that Xylia folded?

	Xylia	Gabby	Difference
Before	1 u + 20	1 u	20
Change	+ 39	+ 29
After	1 u + 59	1 u + 29	30
Comparing between Xylia and Gabby in the end	5 p	3 p	2 p

Difference between the number of paper cranes that Xylia and Gabby folded in the end is repeated.

Difference between the number of paper cranes that Xylia and Gabby folded in the end
= 5 p - 3 p
= 2 p

Difference between the number of paper cranes that Xylia and Gabby folded in the end
= (1 u + 59) - (1 u + 29)
= 1 u + 59 - 1 u - 29
= 59 - 29
= 30

2 p = 30

1 p = 30 ÷ 2 = 15

Number of paper cranes that Xylia folded
= 5 p
= 5 x 15
= 75

Answer(s): 75
