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 2 more 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)
25 of Bryan's stickers → 4 u + 2
15 of Bryan's stickers → (4 u + 2) ÷ 2 = 2 u + 1
55 of Bryan's stickers → 5 x (2 u + 1) = 10 u + 5
Number of Bryan's stickers = 10 u + 5
(c)
Total number of stickers
= 7 u + 10 u + 5
= 17 u + 5
(d)
Difference in the number of stickers between Bryan and Adam
= (10 u + 5) - 7 u
= 10 u - 7 u + 5
= 3 u + 5
Answer(s): (a) 7 u; (b) 10 u + 5; (c) 17 u + 5; (d) 3 u + 5
