Before |
8 x 7 = 56 u |
1 x 7 = 7 u |
9 x 7 = 63 u |
Change |
- 6 |
+ 6 |
|
After |
6 x 9 = 54 u |
1 x 9 = 9 u |
7 x 9 = 63 u |
(a)
Change X times into units.
There is an internal transfer of 6 stickers from Bryan to Adam.
The total remains unchanged.
LCM of 9 and 7 is 63.
Number of stickers that Bryan gives to Adam
= 56 u - 54 u
= 2 u
Difference in the number of stickers between Bryan and Adam at first
= 56 u - 7 u
= 49 u
(b)
Difference in the number of stickers between Bryan and Adam in the end
= 54 u - 9 u
= 45 u
(c)
Difference in the number of stickers that Bryan has at first and in the end
= 56 u - 54 u
= 2 u
(d)
Difference in the number of stickers that Adam has at first and in the end
= 9 u - 7 u
= 2 u
Answer(s): (a) 49; (b) 45; (c) 2; (d) 2
