Answer 1

Ella has 56 marbles, David has 21 marbles, and Jenny has 10 marbles.

Explanation:

Ella has 56 marbles, which is previously given. You take 56 and multiply it by 3/8. This gets 21. This is the amount of marbles David has. subtract 21 from 56 to get the amount Ella has after she gave 21 marbles to David. Ella has 35 marbles after selling 3/8 of her collection to David. Take 35 and multiply it by 2/7. This gets 10. This is the amount of marbles Jenny has.
