Adam has 300 stickers.
³₅ of the stickers are sold in the morning.
¹¹₁₂ of the remaining stickers are sold in the afternoon.
How many more stickers are sold in the afternoon than what are left?
Fraction of stickers left in the morning
= 1 - ³₅

= ²₅

²₅ of total stickers = ¹²₁₂ of remaining stickers

Make the numerators the same.
LCM of 2 and 12 is 12.

^{2 x 6} _{5 x 6} of total stickers = ^{12 x 1}_{12 x 1} of remaining stickers
¹²₃₀ of total stickers = ¹²₁₂ of remaining stickers

Total number of stickers at first = 30 u
Total number of stickers after selling some in the morning = 12 u

Number of stickers sold in the morning = 30 u - 12 u = 18 u
Number of stickers sold in the afternoon = 11 u
Number of stickers left = 12 u - 11 u = 1 u

30 u = 300

1 u = 300 ÷ 30 = 10

Number of more stickers sold in the afternoon than what is left
= 11 u - 1 u
= 10 u
= 10 x 10
= 100

Answer(s): 100
