413 of Adam's stickers is equal to
1213 of Bryan's stickers
Let
113 of Bryan's stickers be 1 u.
- Number of stickers that Bryan has = _____ u
- Number of stickers that Adam has = _____u
- Total number of stickers = _____ u
- Difference in the number of stickers between Bryan and Adam = _____u
(a)
Make the numerators the same.
LCM of 4 and 12 = 12
413 of Adam's stickers =
1213 of Bryan's stickers
4 x 3 13 x 3 of Adam's stickers =
1213 of Bryan's stickers
1239 of Adam's stickers =
1213 of Bryan's stickers
Let
113 of Bryan's stickers be 1 u.
1313 of Bryan's stickers = 13 u
Number of stickers that Bryan has = 13 u
(b)
413 of Adam's sticker =
1213 of Bryan's stickers = 12 u
113 of Adam's stickers = 12 ÷ 4 = 3 u
1313 of Adam's stickers = 3 × 13 = 39 u
Number of stickers that Adam has = 39 u
(c)
Total number of stickers
= 13 u + 39 u
= 52 u
(d)
Difference in the number of stickers between Adam and Bryan
= 39 u - 13 u
= 26 u
Answer(s): (a) 13; (b) 39; (c) 52; (d) 26
