49 of Bryan's stickers is equal to
1213 of Adam's stickers
Let
113 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 12 = 12
49 of Bryan's stickers =
1213 of Adam's stickers
4 x 3 9 x 3 of Bryan's stickers =
1213 of Adam's stickers
1227 of Bryan's stickers =
1213 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)
49 of Bryan's sticker =
1213 of Adam's stickers = 12 u
19 of Bryan's stickers = 12 ÷ 4 = 3 u
99 of Bryan's stickers = 3 × 9 = 27 u
Number of stickers that Bryan has = 27 u
(c)
Total number of stickers
= 13 u + 27 u
= 40 u
(d)
Difference in the number of stickers between Bryan and Adam
= 27 u - 13 u
= 14 u
Answer(s): (a) 13; (b) 27; (c) 40; (d) 14
