Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
23 of the stickers Adam has is 22 less than
89 of what Bryan has.
Let
89 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.
89 of Bryan's stickers → 8 u
19 of Bryan's stickers → 1 u
99 of Bryan's stickers → 9 u
Number of Bryan's stickers = 9 u
(b)
23 of Adam's stickers → 8 u - 22
13 of Adam's stickers → (8 u - 22) ÷ 2 = 4 u - 11
33 of Adam's stickers → 3 x (4 u - 11) = 12 u - 33
Number of Adam's stickers = 12 u - 33
(c)
Total number of stickers
= 9 u + 12 u - 33
= 21 u - 33
(d)
Difference in the number of stickers between Adam and Bryan
= (12 u - 33) - 9 u
= 12 u - 9 u - 33
= 3 u - 33
Answer(s): (a) 9 u; (b) 12 u - 33; (c) 21 u - 33; (d) 3 u - 33
