Fill in the blanks.
Bryan and Adam have some stickers.
23 of Bryan's stickers is equal to
89 of Adam's stickers
Let
19 of Adam's stickers be 1 u.
- Number of stickers that Adam has = _____ u
- Number of stickers that Bryan has = _____u
- Total number of stickers = _____ u
- Difference in the number of stickers between Adam and Bryan = _____u
(a)
Make the numerators the same.
LCM of 2 and 8 = 8
23 of Bryan's stickers =
89 of Adam's stickers
2 x 4 3 x 4 of Bryan's stickers =
89 of Adam's stickers
812 of Bryan's stickers =
89 of Adam's stickers
Let
19 of Adam's stickers be 1 u.
99 of Adam's stickers = 9 u
Number of stickers that Adam has = 9 u
(b)
23 of Bryan's sticker =
89 of Adam's stickers = 8 u
13 of Bryan's stickers = 8 ÷ 2 = 4 u
33 of Bryan's stickers = 4 × 3 = 12 u
Number of stickers that Bryan has = 12 u
(c)
Total number of stickers
= 9 u + 12 u
= 21 u
(d)
Difference in the number of stickers between Bryan and Adam
= 12 u - 9 u
= 3 u
Answer(s): (a) 9; (b) 12; (c) 21; (d) 3
