I think to press enter to see what happens.
example 1
$${\mathtt{0.8}} = {\frac{{\mathtt{4}}}{{\mathtt{5}}}}$$
Example 2
$${\mathtt{0.85}} = {\frac{{\mathtt{17}}}{{\mathtt{20}}}}$$
Example 3
$${\mathtt{0.934}} = {\frac{{\mathtt{467}}}{{\mathtt{500}}}}$$
Example 4
$${\mathtt{0.154\: \!1}} = {\frac{{\mathtt{1\,541}}}{{\mathtt{10\,000}}}}$$
I think this is the final example
Example 5
$${\mathtt{0.879\: \!1}} = {\frac{{\mathtt{8\,791}}}{{\mathtt{10\,000}}}}$$
hope I helped!!!!
