Adam and Bryan have some stickers.
³₄ of Adam's stickers is 18 less than ²₅ of Bryan's stickers.
Bryan has 135 stickers.

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

(a)
Make the numerators the same.
3x24x2 of Adam's stickers = 2x35x3 of Bryan's stickers - 18
68 of Adam's stickers = 615 of Bryan's stickers - 18

Let ¹₁₅ of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 15 u

15 u = 135

1 u = 135 ÷ 15 = 9

⁶₈ of Adam's stickers = 6 u - 18
¹₈ of Adam's stickers = 1 u - 3
⁸₈ of Adam's stickers = 8 u - 24

Number of stickers that Adam has
= 8 u - 24
= 8 x 9 - 24
= 72 - 24
= 48

(b)
Number of stickers that Adam and Bryan have altogether
= 48 + 135
= 183

(c)
Number of stickers that Bryan have more than Adam
= 135 - 48
= 87

Answer(s): (a) 48; (b) 183; (c) 87
