Adam has some stickers
He gives away ¹₃ and an additional 24 stickers to Bryan.
He gives away ¹₉ of the remainder and 22 more stickers to Chris
and ⁴₇ of the rest to David.
Adam has 18 stickers left.
How many stickers does he have at first?
Number of stickers that Adam gives to Bryan = ¹₃ of the total + 24
Number of stickers that Adam gives to Chris = ¹₉ of the remainder + 22
Number of stickers that Adam gives to David = ⁴₇ of the rest
Number of stickers left = 18


Working backwards.
1 - ⁴₇ = ³₇

³₇ of the rest → 18
¹₇ of the rest → 18 ÷ 3 = 6
⁷₇ of the rest → 7 x 6 = 42

1 - ¹₉ = ⁸₉

⁸₉ of the remainder = 22 + 42 = 64
¹₉ of the remainder = 64 ÷ 8 = 8
⁹₉ of the remainder = 9 x 8 = 72

1 - ¹₃ = ²₃
²₃ of the total = 72 + 24 = 96
¹₃ of the total = 96 ÷ 2 = 48
³₃ of the total = 3 x 48 = 144

Number of stickers at first = 144

Answer(s): 144
