Final answer:
Coraline gives to Leo 12 marbles.
Step-by-step explanation:
To find out how many marbles Coraline gives to Leo, we can calculate 3/8 of the total number of marbles that Cool has
Cool has 32 marbles, and Coraline gives Leo 3/8 of these marbles. The calculation is as follows:
Marbles given to Leo = 3/8 * Total marbles
Substitute the given value:
Marbles given to Leo = 3/8 * 32
Now, perform the calculation:
Marbles given to Leo = 3/8 * 32 = 3 * 32/8} = 12
Therefore, Coraline gives to Leo 12 marbles.
