The sum of the numerator and denominator of a simplest fraction is 18. Which fraction is the largest
True fraction refers to the fraction whose numerator is less than the denominator, and the simplest fraction refers to the fraction whose numerator and denominator are mutually prime. A simplest true fraction, the combination of numerator and denominator is 18. Such fractions are: 1 / 17, 5 / 13, 7 / 11, and the largest one is 7 / 11
