Three -eights of the marbles in a box are red. The rest are green. There are 80 green marbles. How many more green marbles are there than red marbles?

3/8 are red 5/8 are green ; there are 80 green marbles , 80 divided by 5 is 16 , so that means that 1/8 is 16 marbles , which means , if 3/8 are red and 3 multiplied by 16 is 48 , there are 48 red marbles.

5/8 = fraction of green marbles. Let Y be the total number of marbles. So 80/Y, 80 is the number of green marbles right? So 80 out of the total number of marbles. Solve for Y... so Y = 128. So there are 128 total marbles. So subtract 128 (total number of marbles) minus 80 (number of green marbles).
Your answer is 48 red marbles.
48/128 is 3/8 when you reduce the fraction.
