After |
2 x 5 = 10 u |
1 x 5 = 5 u |
3 x 5 = 15 u |
(a)
Change X times into units.
There is an internal transfer of 24 stickers from Adam to Bryan.
The total remains unchanged.
LCM of 5 and 3 is 15.
Number of stickers that Adam gives to Bryan
= 12 u - 10 u
= 2 u
Difference in the number of stickers between Adam and Bryan at first
= 12 u - 3 u
= 9 u
(b)
Difference in the number of stickers between Adam and Bryan in the end
= 10 u - 5 u
= 5 u
(c)
Difference in the number of stickers that Adam has at first and in the end
= 12 u - 10 u
= 2 u
(d)
Difference in the number of stickers that Bryan has at first and in the end
= 5 u - 3 u
= 2 u
Answer(s): (a) 9; (b) 5; (c) 2; (d) 2
