Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).

Bryan and Adam have some stickers.
²₅ of the stickers that Bryan has is 10 more than ²₃ of what Adam has.
Let ²₃ of Adam's stickers be 2 u.

1. Number of stickers that Adam has = ___________
2. Number of stickers that Bryan has = ___________
3. Total number of stickers = ___________
4. Difference in the number of stickers between Bryan and Adam = ___________

(a)
Change fraction into units.

²₃ of Adam's stickers → 2 u
¹₃ of Adam's stickers → 1 u
³₃ of Adam's stickers → 3 u

Number of Adam's stickers = 3 u

(b)
²₅ of Bryan's stickers → 2 u + 10
¹₅ of Bryan's stickers → (2 u + 10) ÷ 2 = 1 u + 5
⁵₅ of Bryan's stickers → 5 x (1 u + 5) = 5 u + 25

Number of Bryan's stickers = 5 u + 25

(c)
Total number of stickers
= 3 u + 5 u + 25
= 8 u + 25

(d)
Difference in the number of stickers between Bryan and Adam
= (5 u + 25) - 3 u
= 5 u - 3 u + 25
= 2 u + 25

Answer(s): (a) 3 u; (b) 5 u + 25; (c) 8 u + 25; (d) 2 u + 25
