Adam and Bryan have some stickers.
111 of Adam's stickers is 9 less than
112 of Bryan's stickers.
Let
111 of Adam's stickers be 1 u.
- Number of stickers that Adam has = _____
- Number of stickers that Bryan has = _____
- Total number of stickers = _____
- Difference in the number of stickers between Bryan and Adam = _____
(a)
111 of Adam's stickers = 1 u
1111 of Adam's stickers = 11 u
(b)
112 of Bryan's stickers =
111 of Adam's stickers + 9
112 of Bryan's stickers = 1 u + 9
1212 of Bryan's stickers = 12(1 u + 9) = 12 u + 108
(c)
Total number of stickers
= 11 u + 12 u + 108
= 23 u + 108
(d)
Difference in the number of stickers between Bryan and Adam
= 12 u + 108 - 11 u
= 12 u - 11 u + 108
= 1 u + 108
Answer(s): (a) 11 u; (b) 12 u + 108; (c) 23 u + 108; (d) 1 u + 108
