Emma baked 32 croissants. ⁵₈ of the croissants were peach croissants. The rest were cherry croissants. She gave an equal number of peach croissants and cherry croissants away and had 5 times as many peach croissants as cherry croissants left. How many croissants did she give away?

	Peach croissants	Cherry croissants	Difference
Before	5x2 = 10 u	3x2 = 6 u	2x2 = 4 u
Change	- 5 u	- 5 u
After	5x1 = 5 u	1x1 = 1 u	4x1 = 4 u

Since Emma gave away an equal number of peach croissants and cherry croissants, the difference in the number of peach croissants and cherry croissants remains unchanged.  Make the difference in the peach croissants and cherry croissants the same.  LCM of 2 and 4 is 4.

Total number of croissants at first
= 10 u + 6 u
= 16 u

16 u = 32

1 u = 32 ÷ 16 = 2

Number of croissants that Emma gave away
= 5 u + 5 u
= 10 u
= 10 x 2 
= 20

Answer(s): 20
