Some stickers are in a packet.
If Adam puts them into groups of 9, there are 4 stickers short.
If Adam puts them into groups of 7, there are 6 stickers left.
Find the smallest possible number of stickers in a packet.
Multiples of 9: 9, 18, 27, 36, 45
Multiples of 9 (-4): 5, 14, 23, 32, 41
Multiples of 7: 7, 14, 21, 28, 35
Multiples of 7 (+6): 13, 20, 27, 34, 41
Smallest possible number of stickers in a packet = 41
