Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
512 of the stickers that Adam has is 10 more than
59 of what Bryan has.
Let
59 of Bryan's stickers be 5 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.
59 of Bryan's stickers → 5 u
19 of Bryan's stickers → 1 u
99 of Bryan's stickers → 9 u
Number of Bryan's stickers = 9 u
(b)
512 of Adam's stickers → 5 u + 10
112 of Adam's stickers → (5 u + 10) ÷ 5 = 1 u + 2
1212 of Adam's stickers → 12 x (1 u + 2) = 12 u + 24
Number of Adam's stickers = 12 u + 24
(c)
Total number of stickers
= 9 u + 12 u + 24
= 21 u + 24
(d)
Difference in the number of stickers between Adam and Bryan
= (12 u + 24) - 9 u
= 12 u - 9 u + 24
= 3 u + 24
Answer(s): (a) 9 u; (b) 12 u + 24; (c) 21 u + 24; (d) 3 u + 24
