What is a simpler version of 166,000/186,000?
"Cancelling" the zeroes, we get
166/186 Which, factoring the top and the bottom, we have
(2*83) / (2*93) And cancelling the "2s," we have
83/93
$${\frac{{\mathtt{166}}}{{\mathtt{186}}}} = {\frac{{\mathtt{83}}}{{\mathtt{93}}}} = {\mathtt{0.892\: \!473\: \!118\: \!279\: \!569\: \!9}}$$
