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 10 less than ⁵₈ of what Bryan has.
Let ⁵₈  of Bryan's stickers be 5 u.

1. Number of stickers that Bryan has = ___________
2. Number of stickers that Adam has = ___________
3. Total number of stickers = ___________
4. 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 - 10
¹₁₁ of Adam's stickers → 5 u - 10 = (5 u - 10) ÷ 5 = 1 u - 2 
¹¹₁₁ of Adam's stickers → 11 x (1 u - 2) = 11 u - 22

Number of Adam's stickers = 11 u - 22

(c)
Total number of stickers
= 8 u + 11 u - 22 
= 19 u - 22

(d)
Difference in the number of stickers between Adam and Bryan
= (11 u - 22) - 8 u 
= 11 u - 8 u - 22
= 3 u - 22

Answer(s): (a) 8 u; (b) 11 u - 22; (c) 19 u - 22 ; (d) 3 u - 22
