Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
37 of the stickers that Bryan has is 3 less than
34 of what Adam has.
Let
34 of Adam's stickers be 3 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.
34 of Adam's stickers → 3 u
14 of Adam's stickers → 1 u
44 of Adam's stickers → 4 u
Number of Adam's stickers = 4 u
(b)
37 of Bryan's stickers → 3 u - 3
17 of Bryan's stickers → 3 u - 3 = (3 u - 3) ÷ 3 = 1 u - 1
77 of Bryan's stickers → 7 x (1 u - 1) = 7 u - 7
Number of Bryan's stickers = 7 u - 7
(c)
Total number of stickers
= 4 u + 7 u - 7
= 11 u - 7
(d)
Difference in the number of stickers between Bryan and Adam
= (7 u - 7) - 4 u
= 7 u - 4 u - 7
= 3 u - 7
Answer(s): (a) 4 u; (b) 7 u - 7; (c) 11 u - 7 ; (d) 3 u - 7
