Tommy had some apple wafers and strawberry wafers. ⁵₇ of the number of apple wafers was equal to ¹₅ of the number of strawberry wafers. After Tommy made 9 more apple wafers, the number of apple wafers was ²₅ of the number of strawberry wafers. How many wafers did he have altogether in the end?
Make the numerators the same. LCM of 5 and 1 is 5.

57 of apple wafers = 1x55x5 of strawberry wafers

⁵₇ of apple wafers = ⁵₂₅ of strawberry wafers

	Apple wafers	Strawberry wafers	Total
Before	7 u	25 u
Change	+ 9
After	2x5 = 10 u	5x5 = 25 u	35 u

The number of strawberry wafers remains unchanged.  Make the number of strawberry wafers the same.  LCM of 5 and 25 is 25.

Number of more apple wafers made
= 10 u - 7 u
= 3 u

3 u = 9

1 u = 9 ÷ 3 = 3

Number of wafers that Tommy had in the end
= 10 u + 25 u
= 35 u
= 35 x 3
= 105

Answer(s): 105
