Bryan and Adam have some stickers.
²₃ of Bryan's stickers is 12 less than ³₈ of Adam's stickers.
Adam has 176 stickers.

1. How many stickers does Bryan have?
2. How many stickers do Bryan and Adam have altogether?
3. How many stickers does Adam have more than Bryan?

(a)
Make the numerators the same.
2x33x3 of Bryan's stickers = 3x28x2 of Adam's stickers - 12
69 of Bryan's stickers = 616 of Adam's stickers - 12

Let ¹₁₆ of Adam's stickers be 1 u.
Number of stickers that Adam has = 16 u

16 u = 176

1 u = 176 ÷ 16 = 11

⁶₉ of Bryan's stickers = 6 u - 12
¹₉ of Bryan's stickers = 1 u - 2
⁹₉ of Bryan's stickers = 9 u - 18

Number of stickers that Bryan has
= 9 u - 18
= 9 x 11 - 18
= 99 - 18
= 81

(b)
Number of stickers that Bryan and Adam have altogether
= 9 u - 18 + 16 u
= 81 + 16 x 11
= 81 + 176
= 257

(c)
Number of stickers that Adam have more than Bryan
= 176 - 81
= 95

Answer(s): (a) 81; (b) 257; (c) 95
