Fabian and John gave away the same number of stickers. Fabian gave away ³₅ of his stickers while John gave ⁴₉ of his stickers away. Given that Fabian had 21 stickers less than John at first, how many stickers did Fabian have at first?

	Fabian	John
Before	5x4 = 20 u	9x3 = 27 u
Change	- 3x4 = - 12 u	- 4x3 = - 12 u
After	2x4 = 8 u	5x3 = 15 u

The number of stickers that Fabian and John gave away is the same.  Make the number of stickers that Fabian and John gave away the same. LCM of 3 and 4 is 12.

Number of stickers that Fabian had at first = 20 u
Number of stickers that John had at first = 27 u

Number of stickers that Fabian had less than John at first
= 27 u - 20 u
= 7 u

7 u = 21

1 u = 21 ÷ 7 = 3

Number of stickers that Fabian had at first
= 20 u
= 20 x 3
= 60

Answer(s): 60
