Fill in the blanks.

Bryan and Adam have some stickers.
²₁₃ of Bryan's stickers is equal to ⁴₁₃ of Adam's stickers
Let ¹₁₃ of Adam's stickers be 1 u.

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

(a)
Make the numerators the same.
LCM of 2 and 4 = 4

213 of Bryan's stickers = 413 of Adam's stickers
2 x 2 13 x 2 of Bryan's stickers = 413 of Adam's stickers
426 of Bryan's stickers = 413 of Adam's stickers

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

(b)
²₁₃ of Bryan's sticker = ⁴₁₃ of Adam's stickers = 4 u
¹₁₃ of Bryan's stickers = 4 ÷ 2 = 2 u
¹³₁₃ of Bryan's stickers = 2 × 13 = 26 u

Number of stickers that Bryan has = 26 u

(c)
Total number of stickers
= 13 u + 26 u
= 39 u

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

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