Ann has 48 pieces of chocolate nuggets in a box. She gives one-eigth of the chocolates to her best friend, Mimi. So Mimi has pieces of the chocolate nuggets. Later, Ann eats one-sixth of the remaining chocolates. So, that means, she has eaten pieces of chocolate nuggets. Now there are chocolate nuggets left.

Then, she gives her sisters, Fiona and Finah, one-fifth of her remaining chocolate nuggets to each of them. So each of them has pieces of chocolate nuggets. At the end, Ann has three-fifth of the chocolate nuggets remaining in the box. That means she now has pieces of chocolate nuggets left.
