Lionel had some marbles. He gave $$\frac{7}{12}$$ of them to Paul. He then gave $$\frac{2}{5}$$ of the remainder to Han and $$\frac{1}{10}$$ of remainder to Nick. He kept the rest of the marbles. <hr> If Han got 12 marbles, Lionel has <input min="0" type="number" id ="imp5pg064q4b_1" class="lineinput" placeholder="?" /> marbles at first.
