Fill in the blanks.
Bryan and Adam have some stickers.
27 of Bryan's stickers is equal to
45 of Adam's stickers
Let
15 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 4 = 4
27 of Bryan's stickers =
45 of Adam's stickers
2 x 2 7 x 2 of Bryan's stickers =
45 of Adam's stickers
414 of Bryan's stickers =
45 of Adam's stickers
Let
15 of Adam's stickers be 1 u.
55 of Adam's stickers = 5 u
Number of stickers that Adam has = 5 u
(b)
27 of Bryan's sticker =
45 of Adam's stickers = 4 u
17 of Bryan's stickers = 4 ÷ 2 = 2 u
77 of Bryan's stickers = 2 × 7 = 14 u
Number of stickers that Bryan has = 14 u
(c)
Total number of stickers
= 5 u + 14 u
= 19 u
(d)
Difference in the number of stickers between Bryan and Adam
= 14 u - 5 u
= 9 u
Answer(s): (a) 5; (b) 14; (c) 19; (d) 9
