213 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 2 and 12 = 12
213 of Bryan's stickers =
1213 of Adam's stickers
2 x 6 13 x 6 of Bryan's stickers =
1213 of Adam's stickers
1278 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)
213 of Bryan's sticker =
1213 of Adam's stickers = 12 u
113 of Bryan's stickers = 12 ÷ 2 = 6 u
1313 of Bryan's stickers = 6 × 13 = 78 u
Number of stickers that Bryan has = 78 u
(c)
Total number of stickers
= 13 u + 78 u
= 91 u
(d)
Difference in the number of stickers between Bryan and Adam
= 78 u - 13 u
= 65 u
Answer(s): (a) 13; (b) 78; (c) 91; (d) 65
