Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
211 of the stickers that Adam has is 8 more than
67 of what Bryan has.
Let
67 of Bryan's stickers be 6 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.
67 of Bryan's stickers → 6 u
17 of Bryan's stickers → 1 u
77 of Bryan's stickers → 7 u
Number of Bryan's stickers = 7 u
(b)
211 of Adam's stickers → 6 u + 8
111 of Adam's stickers → (6 u + 8) ÷ 2 = 3 u + 4
1111 of Adam's stickers → 11 x (3 u + 4) = 33 u + 44
Number of Adam's stickers = 33 u + 44
(c)
Total number of stickers
= 7 u + 33 u + 44
= 40 u + 44
(d)
Difference in the number of stickers between Adam and Bryan
= (33 u + 44) - 7 u
= 33 u - 7 u + 44
= 26 u + 44
Answer(s): (a) 7 u; (b) 33 u + 44; (c) 40 u + 44; (d) 26 u + 44
