Fill in the blanks.
Adam and Bryan have some stickers.
215 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 2 and 12 = 12
215 of Adam's stickers =
1213 of Bryan's stickers
2 x 6 15 x 6 of Adam's stickers =
1213 of Bryan's stickers
1290 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)
215 of Adam's sticker =
1213 of Bryan's stickers = 12 u
115 of Adam's stickers = 12 ÷ 2 = 6 u
1515 of Adam's stickers = 6 × 15 = 90 u
Number of stickers that Adam has = 90 u
(c)
Total number of stickers
= 13 u + 90 u
= 103 u
(d)
Difference in the number of stickers between Adam and Bryan
= 90 u - 13 u
= 77 u
Answer(s): (a) 13; (b) 90; (c) 103; (d) 77
