Adam has 350 stickers.
¹₁₀ of the stickers are sold in the morning.
²₃ 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 - ¹₁₀

= ⁹₁₀

⁹₁₀ of total stickers = ³₃ of remaining stickers

Make the numerators the same.
LCM of 9 and 3 is 9.

^{9 x 1} _{10 x 1} of total stickers = ^{3 x 3}_{3 x 3} of remaining stickers
⁹₁₀ of total stickers = ⁹₉ of remaining stickers

Total number of stickers at first = 10 u
Total number of stickers after selling some in the morning = 9 u

Number of stickers sold in the morning = 10 u - 9 u = 1 u
Number of stickers sold in the afternoon = 6 u
Number of stickers left = 9 u - 6 u = 3 u

10 u = 350

1 u = 350 ÷ 10 = 35

Number of more stickers sold in the afternoon than what is left
= 6 u - 3 u
= 3 u
= 3 x 35
= 105

Answer(s): 105
