Fabian had some apricot wafers and apple wafers. ³₁₀ of the number of apricot wafers was equal to ¹₄ of the number of apple wafers. After Fabian made 72 more apricot wafers, the number of apricot wafers was ⁷₃ of the number of apple wafers. How many wafers did he have altogether in the end?
Make the numerators the same. LCM of 3 and 1 is 3.

310 of apricot wafers = 1x34x3 of apple wafers

³₁₀ of apricot wafers = ³₁₂ of apple wafers

	Apricot wafers	Apple wafers	Total
Before	10 u	12 u
Change	+ 72
After	7x4 = 28 u	3x4 = 12 u	40 u

The number of apple wafers remains unchanged.  Make the number of apple wafers the same.  LCM of 3 and 12 is 12.

Number of more apricot wafers made
= 28 u - 10 u
= 18 u

18 u = 72

1 u = 72 ÷ 18 = 4

Number of wafers that Fabian had in the end
= 28 u + 12 u
= 40 u
= 40 x 4
= 160

Answer(s): 160
