Fill in the blanks.
The ratio of Bryan's stickers to Adam's stickers is 5 : 6.
After Bryan gives 95 stickers away,
The ratio of Bryan's stickers to Adam's stickers becomes 1 : 5.
- Whose number of stickers has not changed? Give the answer in number. (Eg Bryan = 1; Adam = 2)
- Number of stickers that Adam has = _____ u
- Change in the number of stickers that Bryan has = _____ u
- 1 u = _____
|
Bryan |
Adam |
Before |
5 x 5 = 25 u |
6 x 5 = 30 u |
Change |
- 95 |
|
After |
1 x 6 = 6 u |
5 x 6 = 30 u |
(a)
Change ratio into units.
The number of stickers that Adam (2) has remains unchanged.
(b)
LCM of 6 and 5 = 30
Number of stickers that Adam has = 30 u
(c)
Change in the number of stickers that Bryan has
= 25 u - 6 u
= 19 u
(d)
Number of stickers that Bryan gives away = 95
19 u = 95
1 u = 95 ÷ 19 = 5
Answer(s): (a) 2; (b) 30; (c) 19; (d) 5
