Esther made some shortbreads. She sold ⁴₅ of them in the afternoon and ²₅ of the remainder in the evening. If she sold 216 more shortbreads in the afternoon than in the evening, how many shortbreads did she make altogether?

Afternoon	Remainder		Total
4x5	1x5		5x5
	Evening	Left
	2	3
20 u	2 u	3 u	25 u

Fraction of shortbreads left after selling some in the afternoon
= 1 - ⁴₅ 
= ¹₅

Fraction of shortbreads sold in the evening
= ²₅ x ¹₅
= ²₂₅

Make the denominators the same.
 ⁴₅ = ²⁰₂₅ 

Number of shortbreads that Esther sold in the afternoon = 20 u
Number of shortbreads that Esther sold in the evening = 2 u

Number of more shortbreads that Esther sold in the afternoon than in the evening
= 20 u - 2 u
= 18 u

18 u = 216

1 u = 216 ÷ 18 = 12

Total number of shortbreads that Esther made
= 25 u
= 25 x 12
= 300

Answer(s): 300
