What is meant by “nearest common fraction”?
A.To help provide great accuracy with rounding and to have simplicity, I round to the nearest common fraction. Common fractions are those ending in commonly used denominators. The number in each denominator value is given a priority. This is only used when a fraction is hard to tell whether it’s closer to another or not. Denominators greater than 100 are rarely used, mainly only if something comes out exact or so close to it and is less than 1000. Odd-balls like 45 [from 90] only occur when a fraction can get reduced. Think of 16/90. This can be reduced to 8/45 and 45 isn’t on the list.
