Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
49 of the stickers that Adam has is 4 more 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)
49 of Adam's stickers → 8 u + 4
19 of Adam's stickers → (8 u + 4) ÷ 4 = 2 u + 1
99 of Adam's stickers → 9 x (2 u + 1) = 18 u + 9
Number of Adam's stickers = 18 u + 9
(c)
Total number of stickers
= 9 u + 18 u + 9
= 27 u + 9
(d)
Difference in the number of stickers between Adam and Bryan
= (18 u + 9) - 9 u
= 18 u - 9 u + 9
= 9 u + 9
Answer(s): (a) 9 u; (b) 18 u + 9; (c) 27 u + 9; (d) 9 u + 9
