Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
25 of the stickers that Adam has is 6 more than
49 of what Bryan has.
Let
49 of Bryan's stickers be 4 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.
49 of Bryan's stickers → 4 u
19 of Bryan's stickers → 1 u
99 of Bryan's stickers → 9 u
Number of Bryan's stickers = 9 u
(b)
25 of Adam's stickers → 4 u + 6
15 of Adam's stickers → (4 u + 6) ÷ 2 = 2 u + 3
55 of Adam's stickers → 5 x (2 u + 3) = 10 u + 15
Number of Adam's stickers = 10 u + 15
(c)
Total number of stickers
= 9 u + 10 u + 15
= 19 u + 15
(d)
Difference in the number of stickers between Adam and Bryan
= (10 u + 15) - 9 u
= 10 u - 9 u + 15
= 1 u + 15
Answer(s): (a) 9 u; (b) 10 u + 15; (c) 19 u + 15; (d) 1 u + 15
