Caden had some chocolate chip wafers and cheese wafers. ⁵₆ of the number of chocolate chip wafers was equal to ¹₈ of the number of cheese wafers. After Caden made 10 more chocolate chip wafers, the number of chocolate chip wafers was ¹₅ of the number of cheese wafers. How many wafers did he have altogether in the end?
Make the numerators the same. LCM of 5 and 1 is 5.

56 of chocolate chip wafers = 1x58x5 of cheese wafers

⁵₆ of chocolate chip wafers = ⁵₄₀ of cheese wafers

	Chocolate chip wafers	Cheese wafers	Total
Before	6 u	40 u
Change	+ 10
After	1x8 = 8 u	5x8 = 40 u	48 u

The number of cheese wafers remains unchanged.  Make the number of cheese wafers the same.  LCM of 5 and 40 is 40.

Number of more chocolate chip wafers made
= 8 u - 6 u
= 2 u

2 u = 10

1 u = 10 ÷ 2 = 5

Number of wafers that Caden had in the end
= 8 u + 40 u
= 48 u
= 48 x 5
= 240

Answer(s): 240
