Fraction of the apple puffs left
= 1 -
17=
67 The number of apple and cheese puffs in the end is the same.
Total number of puffs at first
= 7 u + 6 u + 11
= 13 u + 11
13 u + 11 = 50
13 u = 50 - 11
13 u = 39
1 u = 39 ÷ 13 = 3
Number of cheese puffs at first
= 6 u + 11
= 6 x 3 + 11
= 18 + 11
= 29
Answer(s): 29
