Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
58 of the stickers that Adam has is 10 more than
57 of what Bryan has.
Let
57 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.
57 of Bryan's stickers → 5 u
17 of Bryan's stickers → 1 u
77 of Bryan's stickers → 7 u
Number of Bryan's stickers = 7 u
(b)
58 of Adam's stickers → 5 u + 10
18 of Adam's stickers → (5 u + 10) ÷ 5 = 1 u + 2
88 of Adam's stickers → 8 x (1 u + 2) = 8 u + 16
Number of Adam's stickers = 8 u + 16
(c)
Total number of stickers
= 7 u + 8 u + 16
= 15 u + 16
(d)
Difference in the number of stickers between Adam and Bryan
= (8 u + 16) - 7 u
= 8 u - 7 u + 16
= 1 u + 16
Answer(s): (a) 7 u; (b) 8 u + 16; (c) 15 u + 16; (d) 1 u + 16
