10 marbles represent 50% of the marbles. To get this, turn the percent into a decimal. 50% equals 0.50. You the multiply the total amount of marbles (20) by the decimal, equaling 10 marbles.

The answer is 10.

Because you need the number that represents 50% of all the marbles. so you have to add them all up:

3+8+4+5=20

50% means half, which means you have to divide the total by 2.

20÷2=10
