Abi made some croissants. She sold ³₄ of them in the morning and ³₅ of the remainder in the afternoon. If she sold 72 more croissants in the morning than in the afternoon, how many croissants did she make altogether?

Morning	Remainder		Total
3x5	1x5		4x5
	Afternoon	Left
	3	2
15 u	3 u	2 u	20 u

Fraction of croissants left after selling some in the morning
= 1 - ³₄ 
= ¹₄

Fraction of croissants sold in the afternoon
= ³₅ x ¹₄
= ³₂₀

Make the denominators the same.
 ³₄ = ¹⁵₂₀ 

Number of croissants that Abi sold in the morning = 15 u
Number of croissants that Abi sold in the afternoon = 3 u

Number of more croissants that Abi sold in the morning than in the afternoon
= 15 u - 3 u
= 12 u

12 u = 72

1 u = 72 ÷ 12 = 6

Total number of croissants that Abi made
= 20 u
= 20 x 6
= 120

Answer(s): 120
