Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
23 of the stickers Bryan has is 14 less than
45 of what Adam has.
Let
45 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.
45 of Adam's stickers → 4 u
15 of Adam's stickers → 1 u
55 of Adam's stickers → 5 u
Number of Adam's stickers = 5 u
(b)
23 of Bryan's stickers → 4 u - 14
13 of Bryan's stickers → (4 u - 14) ÷ 2 = 2 u - 7
33 of Bryan's stickers → 3 x (2 u - 7) = 6 u - 21
Number of Bryan's stickers = 6 u - 21
(c)
Total number of stickers
= 5 u + 6 u - 21
= 11 u - 21
(d)
Difference in the number of stickers between Bryan and Adam
= (6 u - 21) - 5 u
= 6 u - 5 u - 21
= 1 u - 21
Answer(s): (a) 5 u; (b) 6 u - 21; (c) 11 u - 21; (d) 1 u - 21
