Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
611 of the stickers that Adam has is 6 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)
611 of Adam's stickers → 6 u + 6
111 of Adam's stickers → (6 u + 6) ÷ 6 = 1 u + 1
1111 of Adam's stickers → 11 x (1 u + 1) = 11 u + 11
Number of Adam's stickers = 11 u + 11
(c)
Total number of stickers
= 7 u + 11 u + 11
= 18 u + 11
(d)
Difference in the number of stickers between Adam and Bryan
= (11 u + 11) - 7 u
= 11 u - 7 u + 11
= 4 u + 11
Answer(s): (a) 7 u; (b) 11 u + 11; (c) 18 u + 11; (d) 4 u + 11
