Adam and Bryan have some stickers.
23 of Adam's stickers is 60 less than
38 of Bryan's stickers.
Bryan has 256 stickers.
- How many stickers does Adam have?
- How many stickers do Adam and Bryan have altogether?
- How many stickers does Bryan have more than Adam?
(a)
Make the numerators the same.
2x33x3 of Adam's stickers =
3x28x2 of Bryan's stickers - 60
69 of Adam's stickers =
616 of Bryan's stickers - 60
Let
116 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 16 u
16 u = 256
1 u = 256 ÷ 16 = 16
69 of Adam's stickers = 6 u - 60
19 of Adam's stickers = 1 u - 10
99 of Adam's stickers = 9 u - 90
Number of stickers that Adam has
= 9 u - 90
= 9 x 16 - 90
= 144 - 90
= 54
(b)
Number of stickers that Adam and Bryan have altogether
= 9 u - 90 + 16 u
= 54 + 16 x 16
= 54 + 256
= 310
(c)
Number of stickers that Bryan have more than Adam
= 256 - 54
= 202
Answer(s): (a) 54; (b) 310; (c) 202
