Fill in the blanks.
Adam and Bryan have some stickers.
213 of Adam's stickers is equal to
1415 of Bryan's stickers
Let
115 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 2 and 14 = 14
213 of Adam's stickers =
1415 of Bryan's stickers
2 x 7 13 x 7 of Adam's stickers =
1415 of Bryan's stickers
1491 of Adam's stickers =
1415 of Bryan's stickers
Let
115 of Bryan's stickers be 1 u.
1515 of Bryan's stickers = 15 u
Number of stickers that Bryan has = 15 u
(b)
213 of Adam's sticker =
1415 of Bryan's stickers = 14 u
113 of Adam's stickers = 14 ÷ 2 = 7 u
1313 of Adam's stickers = 7 × 13 = 91 u
Number of stickers that Adam has = 91 u
(c)
Total number of stickers
= 15 u + 91 u
= 106 u
(d)
Difference in the number of stickers between Adam and Bryan
= 91 u - 15 u
= 76 u
Answer(s): (a) 15; (b) 91; (c) 106; (d) 76
