8 1/3% of Jar B’s marbles need to be moved to jar A to make them equal. This is because:

If Jar A has 100 marbles and B has 120 marbles which is 20% more than Jar A then 10 marbles would have to be moved from Jar B to Jar A. To calculate the percentage it would be 10/120 which reduces to .0833 repeating or 8 1/3%.

Hope this helps :)
