Answer:

  • 1 7/12 is simplest form as a mixed number
  • 19/12 is simplest form as an improper fraction

Explanation:

A fraction is in simplest form when any common factors in the numerator and denominator have been factored out (cancelled). The fraction 7/12 has no common factors in the numerator and denominator. (7 is a prime number, and 12 = 2²·3 is not a multiple of 7.) Hence, the fraction 7/12 is in simplest form.

When the fraction is part of a mixed number, that mixed number is in simplest form when the fraction is. Here, 1 7/12 is in simplest form.

__

The integer portion of a mixed number can be expressed over the fraction's denominator by multiplying it by 1 in the form (denominator)/(denominator).


1(7)/(12)=1*(12)/(12)+(7)/(12)=(1*12+7)/(12)=(19)/(12)

Since the fraction 7/12 is in simplest form, this improper fraction is in simplest form. 19/12 is the simplest form of 1 7/12 when expressed as an improper fraction.
