Adam has some stickers
He gives away ¹₅ and an additional 56 stickers to Bryan.
He gives away ⁵₈ of the remainder and 12 more stickers to Chris
and ³₅ of the rest to David.
Adam has 12 stickers left.
How many stickers does he have at first?
Number of stickers that Adam gives to Bryan = ¹₅ of the total + 56
Number of stickers that Adam gives to Chris = ⁵₈ of the remainder + 12
Number of stickers that Adam gives to David = ³₅ of the rest
Number of stickers left = 12


Working backwards.
1 - ³₅ = ²₅

²₅ of the rest → 12
¹₅ of the rest → 12 ÷ 2 = 6
⁵₅ of the rest → 5 x 6 = 30

1 - ⁵₈ = ³₈

³₈ of the remainder = 12 + 30 = 42
¹₈ of the remainder = 42 ÷ 3 = 14
⁸₈ of the remainder = 8 x 14 = 112

1 - ¹₅ = ⁴₅
⁴₅ of the total = 112 + 56 = 168
¹₅ of the total = 168 ÷ 4 = 42
⁵₅ of the total = 5 x 42 = 210

Number of stickers at first = 210

Answer(s): 210
