We can divide each digit by 7. So 56/7=8 and 21/7=3
so.... 8:3
I think the answer would be C because variability means average.
Each friend would have taken a total of 35 rides each.
This can be verified by multiplying 35 by 35 to get 1225.
Ok so…
The answer is: 15 more marbles
Because
18 divided by 2 is 9
15+9=24
Now Chris has 9
Kevin has 24
24-9=15
Hope this helps:)
