Yoko and Pamela folded paper balls over two days. On Wednesday, Yoko folded 6 paper balls more than Pamela. On Thursday, Yoko folded another 38 paper balls and Pamela folded another 8. At the end of the two days, Yoko made ⁷₁₀ of the total number of balls. What was the number of paper balls that Yoko folded?

	Yoko	Pamela	Difference
Before	1 u + 6	1 u	6
Change	+ 38	+ 8
After	1 u + 44	1 u + 8	36
Comparing between Yoko and Pamela in the end	7 p	3 p	4 p

Difference between the number of paper balls that Yoko and Pamela folded in the end is repeated.

Difference between the number of paper balls that Yoko and Pamela folded in the end
= 7 p - 3 p
= 4 p

Difference between the number of paper balls that Yoko and Pamela folded in the end
= (1 u + 44) - (1 u + 8)
= 1 u + 44 - 1 u - 8
= 44 - 8
= 36

4 p = 36

1 p = 36 ÷ 4 = 9

Number of paper balls that Yoko folded
= 7 p
= 7 x 9
= 63

Answer(s): 63
