Each of the 4 girls will get 3 marbles with 1 left over.
If 4 girls get 3 marbles each, that is 4 times 3. This is 12. Now since there are 13 marbles, we know that there is 2 left over because 13-12 is 1.
To figure out what a fraction is as a decimal u would do the top divided by the bottom
For this fraction it would look like this,
8 divided by 9 which would get you 0.88888888888
So your decimal is 0.889
Its not 0.888 because with decimals since a typical decimal is show as 2-3 numbers it would be rounded up to keep it as 3 numbers or less. so this would be 0.889 or if that doesnt work 0.888 with a line over the last 8.
