Sabrina made 104 more pandan croissants than apple croissants. After she gave away ⁵₇ of the pandan croissants and ¹₄ of the apple croissants, there were an equal number of pandan croissants and apple croissants left. How many pandan croissants did she give away?

	Pandan croissants	Apple croissants	Difference
Before	7x3 = 21 u	4x2 = 8 u	13 u
Change	- 5x3 = - 15 u	- 1x2 = - 2 u
After	2x3 = 6 u	3x2 = 6 u

Fraction of pandan croissants left
= 1 - ⁵₇
= ²₇

Fraction of apple croissants left
= 1 - ¹₄
= ³₄

The number of pandan croissants and apple croissants in the end is the same. Make the numerators the same.  LCM of 3 and 2 is 6.

²₇ of pandan croissants = ³₄ of apple croissants
⁶₂₁ of pandan croissants = ⁶₈ of apple croissants

Number of more pandan croissants than apple croissants at first
= 21 u - 8 u
= 13 u

13 u = 104

1 u = 104 ÷ 13 = 8

Number of pandan croissants that Sabrina gave away
= 21 u - 6 u
= 15 u
= 15 x 8
= 120

Answer(s): 120
