Howard and Ryan gave away the same number of stickers. Howard gave away ⁶₁₁ of his stickers while Ryan gave ⁴₉ of his stickers away. Given that Howard had 15 stickers less than Ryan at first, how many stickers did Howard have at first?

	Howard	Ryan
Before	11x2 = 22 u	9x3 = 27 u
Change	- 6x2 = - 12 u	- 4x3 = - 12 u
After	5x2 = 10 u	5x3 = 15 u

The number of stickers that Howard and Ryan gave away is the same.  Make the number of stickers that Howard and Ryan gave away the same. LCM of 6 and 4 is 12.

Number of stickers that Howard had at first = 22 u
Number of stickers that Ryan had at first = 27 u

Number of stickers that Howard had less than Ryan at first
= 27 u - 22 u
= 5 u

5 u = 15

1 u = 15 ÷ 5 = 3

Number of stickers that Howard had at first
= 22 u
= 22 x 3
= 66

Answer(s): 66
