Fill in the blanks.
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.
18 of Bryan's stickers is 11 less than
111 of Adam's stickers.
Let
18 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)
18 of Bryan's stickers = 1 u
88 of Bryan's stickers = 8 u
(b)
111 of Adam's stickers =
18 of Bryan's stickers + 11
111 of Adam's stickers = 1 u + 11
1111 of Adam's stickers = 11(1 u + 11) = 11 u + 121
(c)
Total number of stickers
= 8 u + 11 u + 121
= 19 u + 121
(d)
Difference in the number of stickers between Adam and Bryan
= 11 u + 121 - 8 u
= 11 u - 8 u + 121
= 3 u + 121
Answer(s): (a) 8 u; (b) 11 u + 121; (c) 19 u + 121; (d) 3 u + 121
