Well, first you would make 1 1/16 into a inproper fraction(17/16), then do multiplacation.$$\left({\frac{{\mathtt{4}}}{{\mathtt{5}}}}\right){\mathtt{\,\times\,}}\left({\frac{{\mathtt{17}}}{{\mathtt{16}}}}\right) = {\frac{{\mathtt{17}}}{{\mathtt{20}}}} = {\mathtt{0.85}}$$

$${\frac{\left({\left({\mathtt{1.5}}{\mathtt{\,\times\,}}{\mathtt{10}}\right)}^{{\mathtt{25}}}\right)}{\left({\mathtt{6.02}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{23}}}\right)}} = {\mathtt{419\,454.622\: \!824\: \!623\: \!735\: \!244\: \!1}}$$, Hopefully, this is what you meant.  I have NO IDEA what order of operation you were talking about.

Well, because 1/3 is 0.33... , then 2/3 is 0.66... ,So you would have the fraction be 13 2/3. 

Answer: 13 2/3

 To be exact:$${\mathtt{22\,521\,008\,071\,930\,811\,247\,210\,364\,724\,710\,555\,878\,336\,746\,262\,578\,603\,045\,969\,925\,706\,618\,268\,298\,469\,415\,658\,031\,134\,405\,487.242\: \!341\: \!214\: \!456\: \!877\: \!8}} \approx {\mathtt{2.2521008071930811\times 10^{94}}}$$
