Adam and Bryan have some stickers.
45 of Adam's stickers is 44 more than
13 of Bryan's stickers.
Bryan has 180 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 43 x 4 of Bryan's stickers + 44
45 of Adam's stickers =
412 of Bryan's stickers + 44
Let
112 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 12 u
12 u = 180
1 u = 180 ÷ 12 = 15
45 of Adam's stickers = 4 u + 44
15 of Adam's stickers = 1 u + 11
55 of Adam's stickers = 5 u + 55
Number of stickers that Adam has
= 5 u + 55
= 5 x 15 + 55
= 75 + 55
= 130
(b)
Number of stickers that Adam and Bryan have altogether
= 130 + 180
= 310
(c)
Number of stickers that Bryan has more than Adam
= 180 - 130
= 50
Answer(s): (a) 130; (b) 310; (c) 50
