Fill in the blanks.

Adam and Bryan have some stickers.
²₁₃ of Adam's stickers is equal to ⁶₁₃ of Bryan's stickers
Let ¹₁₃ of Bryan's stickers be 1 u.

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

(a)
Make the numerators the same.
LCM of 2 and 6 = 6

213 of Adam's stickers = 613 of Bryan's stickers
2 x 3 13 x 3 of Adam's stickers = 613 of Bryan's stickers
639 of Adam's stickers = 613 of Bryan's stickers

Let ¹₁₃ of Bryan's stickers be 1 u.
¹³₁₃ of Bryan's stickers = 13 u
Number of stickers that Bryan has = 13 u

(b)
²₁₃ of Adam's sticker = ⁶₁₃ of Bryan's stickers = 6 u
¹₁₃ of Adam's stickers = 6 ÷ 2 = 3 u
¹³₁₃ of Adam's stickers = 3 × 13 = 39 u

Number of stickers that Adam has = 39 u

(c)
Total number of stickers
= 13 u + 39 u
= 52 u

(d)
Difference in the number of stickers between Adam and Bryan
= 39 u - 13 u
= 26 u

Answer(s): (a) 13; (b) 39; (c) 52; (d) 26
