Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
25 of the stickers that Adam has is 8 more than
811 of what Bryan has.
Let
811 of Bryan's stickers be 8 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.
811 of Bryan's stickers → 8 u
111 of Bryan's stickers → 1 u
1111 of Bryan's stickers → 11 u
Number of Bryan's stickers = 11 u
(b)
25 of Adam's stickers → 8 u + 8
15 of Adam's stickers → (8 u + 8) ÷ 2 = 4 u + 4
55 of Adam's stickers → 5 x (4 u + 4) = 20 u + 20
Number of Adam's stickers = 20 u + 20
(c)
Total number of stickers
= 11 u + 20 u + 20
= 31 u + 20
(d)
Difference in the number of stickers between Adam and Bryan
= (20 u + 20) - 11 u
= 20 u - 11 u + 20
= 9 u + 20
Answer(s): (a) 11 u; (b) 20 u + 20; (c) 31 u + 20; (d) 9 u + 20
