Adam and Bryan have some stickers.
45 of Adam's stickers is 20 more than
14 of Bryan's stickers.
Bryan has 400 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.
4 x 15 x 1 of Adam's stickers =
1 x 44 x 4 of Bryan's stickers + 20
45 of Adam's stickers =
416 of Bryan's stickers + 20
Let
116 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 16 u
16 u = 400
1 u = 400 ÷ 16 = 25
45 of Adam's stickers = 4 u + 20
15 of Adam's stickers = 1 u + 5
55 of Adam's stickers = 5 u + 25
Number of stickers that Adam has
= 5 u + 25
= 5 x 25 + 25
= 125 + 25
= 150
(b)
Number of stickers that Adam and Bryan have altogether
= 150 + 400
= 550
(c)
Number of stickers that Bryan has more than Adam
= 400 - 150
= 250
Answer(s): (a) 150; (b) 550; (c) 250
