Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
511 of the stickers that Adam has is 5 less than
58 of what Bryan has.
Let
58 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.
58 of Bryan's stickers → 5 u
18 of Bryan's stickers → 1 u
88 of Bryan's stickers → 8 u
Number of Bryan's stickers = 8 u
(b)
511 of Adam's stickers → 5 u - 5
111 of Adam's stickers → 5 u - 5 = (5 u - 5) ÷ 5 = 1 u - 1
1111 of Adam's stickers → 11 x (1 u - 1) = 11 u - 11
Number of Adam's stickers = 11 u - 11
(c)
Total number of stickers
= 8 u + 11 u - 11
= 19 u - 11
(d)
Difference in the number of stickers between Adam and Bryan
= (11 u - 11) - 8 u
= 11 u - 8 u - 11
= 3 u - 11
Answer(s): (a) 8 u; (b) 11 u - 11; (c) 19 u - 11 ; (d) 3 u - 11
