Fill in the blanks.
Adam and Bryan have some stickers.
215 of Adam's stickers is equal to
411 of Bryan's stickers
Let
111 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 4 = 4
215 of Adam's stickers =
411 of Bryan's stickers
2 x 2 15 x 2 of Adam's stickers =
411 of Bryan's stickers
430 of Adam's stickers =
411 of Bryan's stickers
Let
111 of Bryan's stickers be 1 u.
1111 of Bryan's stickers = 11 u
Number of stickers that Bryan has = 11 u
(b)
215 of Adam's sticker =
411 of Bryan's stickers = 4 u
115 of Adam's stickers = 4 ÷ 2 = 2 u
1515 of Adam's stickers = 2 × 15 = 30 u
Number of stickers that Adam has = 30 u
(c)
Total number of stickers
= 11 u + 30 u
= 41 u
(d)
Difference in the number of stickers between Adam and Bryan
= 30 u - 11 u
= 19 u
Answer(s): (a) 11; (b) 30; (c) 41; (d) 19
