At the end of the two days, Fanny made ⁷₁₀ of the total number of balls. What was the number of paper balls that Victoria folded?

	Fanny	Victoria	Difference
Before	1 u + 15	1 u	15
Change	+ 22	+ 1
After	1 u + 37	1 u + 1	36
Comparing between Fanny and Victoria in the end	7 p	3 p	4 p

Difference between the number of paper balls that Fanny and Victoria folded in the end is repeated.

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

Difference between the number of paper balls that Fanny and Victoria folded in the end
= (1 u + 37) - (1 u + 1)
= 1 u + 37 - 1 u - 1
= 37 - 1
= 36

4 p = 36

1 p = 36 ÷ 4 = 9

Number of paper balls that Victoria folded
= 3 p
= 3 x 9
= 27

Answer(s): 27
