For (a) to (d), give the answers in units (Eg 1 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
110 of Bryan's stickers is 9 less than
111 of Adam's stickers.
Let
110 of Bryan's stickers be 1 u.
- Number of stickers that Bryan has = _____
- Number of stickers that Adam has = _____
- Total number of stickers = _____
- Difference in the number of stickers between Adam and Bryan = _____
(a)
110 of Bryan's stickers = 1 u
1010 of Bryan's stickers = 10 u
(b)
111 of Adam's stickers =
110 of Bryan's stickers + 9
111 of Adam's stickers = 1 u + 9
1111 of Adam's stickers = 11(1 u + 9) = 11 u + 99
(c)
Total number of stickers
= 10 u + 11 u + 99
= 21 u + 99
(d)
Difference in the number of stickers between Adam and Bryan
= 11 u + 99 - 10 u
= 11 u - 10 u + 99
= 1 u + 99
Answer(s): (a) 10 u; (b) 11 u + 99; (c) 21 u + 99; (d) 1 u + 99
