As we all know, if a positive fractional value is added to the numerator and denominator of the fraction, the fraction a/b (b is greater than A and greater than 0) will change.

The result will increase! For example, there is a cup of sugar water with a total mass of B and a sugar content of A! Then the sugar content percentage of this cup of syrup is: a/b *%! If you add some sugar, let the added sugar mass be C, because the sugar water becomes sweet, of course: (a+c)/(b+c) > A/b！
