After |
6 x 10 = 60 u |
1 x 10 = 10 u |
7 x 10 = 70 u |
(a)
Change X times into units.
There is an internal transfer of 27 stickers from Bryan to Adam.
The total remains unchanged.
LCM of 10 and 7 is 70.
Number of stickers that Bryan gives to Adam
= 63 u - 60 u
= 3 u
Difference in the number of stickers between Bryan and Adam at first
= 63 u - 7 u
= 56 u
(b)
Difference in the number of stickers between Bryan and Adam in the end
= 60 u - 10 u
= 50 u
(c)
Difference in the number of stickers that Bryan has at first and in the end
= 63 u - 60 u
= 3 u
(d)
Difference in the number of stickers that Adam has at first and in the end
= 10 u - 7 u
= 3 u
Answer(s): (a) 56; (b) 50; (c) 3; (d) 3
