Fill in the blanks.
Bryan and Adam have some stickers.
415 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 4 and 8 = 8
415 of Bryan's stickers =
89 of Adam's stickers
4 x 2 15 x 2 of Bryan's stickers =
89 of Adam's stickers
830 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)
415 of Bryan's sticker =
89 of Adam's stickers = 8 u
115 of Bryan's stickers = 8 ÷ 4 = 2 u
1515 of Bryan's stickers = 2 × 15 = 30 u
Number of stickers that Bryan has = 30 u
(c)
Total number of stickers
= 9 u + 30 u
= 39 u
(d)
Difference in the number of stickers between Bryan and Adam
= 30 u - 9 u
= 21 u
Answer(s): (a) 9; (b) 30; (c) 39; (d) 21
