Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
34 of the stickers that Adam has is 9 more than
910 of what Bryan has.
Let
910 of Bryan's stickers be 9 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.
910 of Bryan's stickers → 9 u
110 of Bryan's stickers → 1 u
1010 of Bryan's stickers → 10 u
Number of Bryan's stickers = 10 u
(b)
34 of Adam's stickers → 9 u + 9
14 of Adam's stickers → (9 u + 9) ÷ 3 = 3 u + 3
44 of Adam's stickers → 4 x (3 u + 3) = 12 u + 12
Number of Adam's stickers = 12 u + 12
(c)
Total number of stickers
= 10 u + 12 u + 12
= 22 u + 12
(d)
Difference in the number of stickers between Adam and Bryan
= (12 u + 12) - 10 u
= 12 u - 10 u + 12
= 2 u + 12
Answer(s): (a) 10 u; (b) 12 u + 12; (c) 22 u + 12; (d) 2 u + 12
