Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
29 of the stickers Bryan has is 18 less than
47 of what Adam has.
Let
47 of Adam's stickers be 4 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)
Change fraction into units.
47 of Adam's stickers → 4 u
17 of Adam's stickers → 1 u
77 of Adam's stickers → 7 u
Number of Adam's stickers = 7 u
(b)
29 of Bryan's stickers → 4 u - 18
19 of Bryan's stickers → (4 u - 18) ÷ 2 = 2 u - 9
99 of Bryan's stickers → 9 x (2 u - 9) = 18 u - 81
Number of Bryan's stickers = 18 u - 81
(c)
Total number of stickers
= 7 u + 18 u - 81
= 25 u - 81
(d)
Difference in the number of stickers between Bryan and Adam
= (18 u - 81) - 7 u
= 18 u - 7 u - 81
= 11 u - 81
Answer(s): (a) 7 u; (b) 18 u - 81; (c) 25 u - 81; (d) 11 u - 81
