6 x 11 = 66 u |
1 x 11 = 11 u |
7 x 11 = 77 u |
(a)
Change X times into units.
There is an internal transfer of 28 stickers from Bryan to Adam.
The total remains unchanged.
LCM of 11 and 7 is 77.
Number of stickers that Bryan gives to Adam
= 70 u - 66 u
= 4 u
Difference in the number of stickers between Bryan and Adam at first
= 70 u - 7 u
= 63 u
(b)
Difference in the number of stickers between Bryan and Adam in the end
= 66 u - 11 u
= 55 u
(c)
Difference in the number of stickers that Bryan has at first and in the end
= 70 u - 66 u
= 4 u
(d)
Difference in the number of stickers that Adam has at first and in the end
= 11 u - 7 u
= 4 u
Answer(s): (a) 63; (b) 55; (c) 4; (d) 4
