Yoko made some shortbreads. She sold ³₄ of them in the morning and ⁵₇ of the remainder in the evening. If she sold 176 more shortbreads in the morning than in the evening, how many shortbreads did she make altogether?

Morning	Remainder		Total
3x7	1x7		4x7
	Evening	Left
	5	2
21 u	5 u	2 u	28 u

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

Fraction of shortbreads sold in the evening
= ⁵₇ x ¹₄
= ⁵₂₈

Make the denominators the same.
 ³₄ = ²¹₂₈ 

Number of shortbreads that Yoko sold in the morning = 21 u
Number of shortbreads that Yoko sold in the evening = 5 u

Number of more shortbreads that Yoko sold in the morning than in the evening
= 21 u - 5 u
= 16 u

16 u = 176

1 u = 176 ÷ 16 = 11

Total number of shortbreads that Yoko made
= 28 u
= 28 x 11
= 308

Answer(s): 308
