Bryan and Adam have some stickers.
23 of Bryan's stickers is 36 less than
38 of Adam's stickers.
Adam has 192 stickers.
- How many stickers does Bryan have?
- How many stickers do Bryan and Adam have altogether?
- How many stickers does Adam have more than Bryan?
(a)
Make the numerators the same.
2x33x3 of Bryan's stickers =
3x28x2 of Adam's stickers - 36
69 of Bryan's stickers =
616 of Adam's stickers - 36
Let
116 of Adam's stickers be 1 u.
Number of stickers that Adam has = 16 u
16 u = 192
1 u = 192 ÷ 16 = 12
69 of Bryan's stickers = 6 u - 36
19 of Bryan's stickers = 1 u - 6
99 of Bryan's stickers = 9 u - 54
Number of stickers that Bryan has
= 9 u - 54
= 9 x 12 - 54
= 108 - 54
= 54
(b)
Number of stickers that Bryan and Adam have altogether
= 9 u - 54 + 16 u
= 54 + 16 x 12
= 54 + 192
= 246
(c)
Number of stickers that Adam have more than Bryan
= 192 - 54
= 138
Answer(s): (a) 54; (b) 246; (c) 138
