Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
25 of the stickers that Bryan has is 4 more than
23 of what Adam has.
Let
23 of Adam's stickers be 2 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.
23 of Adam's stickers → 2 u
13 of Adam's stickers → 1 u
33 of Adam's stickers → 3 u
Number of Adam's stickers = 3 u
(b)
25 of Bryan's stickers → 2 u + 4
15 of Bryan's stickers → (2 u + 4) ÷ 2 = 1 u + 2
55 of Bryan's stickers → 5 x (1 u + 2) = 5 u + 10
Number of Bryan's stickers = 5 u + 10
(c)
Total number of stickers
= 3 u + 5 u + 10
= 8 u + 10
(d)
Difference in the number of stickers between Bryan and Adam
= (5 u + 10) - 3 u
= 5 u - 3 u + 10
= 2 u + 10
Answer(s): (a) 3 u; (b) 5 u + 10; (c) 8 u + 10; (d) 2 u + 10
