what is 27/72 x 16/72
$${\frac{{\frac{{\mathtt{27}}}{{\mathtt{72}}}}{\mathtt{\,\times\,}}{\mathtt{16}}}{{\mathtt{72}}}} = {\frac{{\mathtt{1}}}{{\mathtt{12}}}} = {\mathtt{0.083\: \!333\: \!333\: \!333\: \!333\: \!3}}$$
27*16 = 432
72*72 = 144*36 = 5184
432/5184 = 1/12
hope thats not a x.....0.08333333333 would be the answer if its not
