The denominators of English fractions are generally expressed as ordinal numbers, in the plural if the numerator is not 1. (For example, 2/5 and 3/5 are both read as a number of "fifths".) Exceptions include the denominator 2, which is always read "half" or "halves", the denominator 4, which may be alternatively expressed as "quarter"/"quarters" or as "fourth"/"fourths", and the denominator 100, which may be alternatively expressed as "hundredth"/"hundredths" or "percent".

Expand the left hand side to get



28x+12 = 19


Subtract 12 from both sides:



28x = 19-12 = 7


Divide both sides by 28:



x = (7)/(28) = (1)/(4)
