Adam and Bryan have some stickers.
23 of Adam's stickers is 30 less than
38 of Bryan's stickers.
Bryan has 272 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 - 30
69 of Adam's stickers =
616 of Bryan's stickers - 30
Let
116 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 16 u
16 u = 272
1 u = 272 ÷ 16 = 17
69 of Adam's stickers = 6 u - 30
19 of Adam's stickers = 1 u - 5
99 of Adam's stickers = 9 u - 45
Number of stickers that Adam has
= 9 u - 45
= 9 x 17 - 45
= 153 - 45
= 108
(b)
Number of stickers that Adam and Bryan have altogether
= 9 u - 45 + 16 u
= 108 + 16 x 17
= 108 + 272
= 380
(c)
Number of stickers that Bryan have more than Adam
= 272 - 108
= 164
Answer(s): (a) 108; (b) 380; (c) 164
