Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
37 of the stickers that Adam has is 6 less than
34 of what Bryan has.
Let
34 of Bryan's stickers be 3 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.
34 of Bryan's stickers → 3 u
14 of Bryan's stickers → 1 u
44 of Bryan's stickers → 4 u
Number of Bryan's stickers = 4 u
(b)
37 of Adam's stickers → 3 u - 6
17 of Adam's stickers → 3 u - 6 = (3 u - 6) ÷ 3 = 1 u - 2
77 of Adam's stickers → 7 x (1 u - 2) = 7 u - 14
Number of Adam's stickers = 7 u - 14
(c)
Total number of stickers
= 4 u + 7 u - 14
= 11 u - 14
(d)
Difference in the number of stickers between Adam and Bryan
= (7 u - 14) - 4 u
= 7 u - 4 u - 14
= 3 u - 14
Answer(s): (a) 4 u; (b) 7 u - 14; (c) 11 u - 14 ; (d) 3 u - 14
