Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
37 of the stickers that Adam has is 3 more than
35 of what Bryan has.
Let
35 of Bryan's stickers be 3 u.
- Number of stickers that Bryan has = ___________
- Number of stickers that Adam has = ___________
- Total number of stickers = ___________
- Difference in the number of stickers between Adam and Bryan = ___________
(a)
Change fraction into units.
35 of Bryan's stickers → 3 u
15 of Bryan's stickers → 1 u
55 of Bryan's stickers → 5 u
Number of Bryan's stickers = 5 u
(b)
37 of Adam's stickers → 3 u + 3
17 of Adam's stickers → (3 u + 3) ÷ 3 = 1 u + 1
77 of Adam's stickers → 7 x (1 u + 1) = 7 u + 7
Number of Adam's stickers = 7 u + 7
(c)
Total number of stickers
= 5 u + 7 u + 7
= 12 u + 7
(d)
Difference in the number of stickers between Adam and Bryan
= (7 u + 7) - 5 u
= 7 u - 5 u + 7
= 2 u + 7
Answer(s): (a) 5 u; (b) 7 u + 7; (c) 12 u + 7; (d) 2 u + 7
