Simplify the operation

Reduce (simplify) the fractions to their lowest terms equivalents:

  • A fully reduced (simplified) fraction is one with the smallest possible numerator and denominator, one that can no longer be reduced, and it is called an irreducible fraction.
  • * By reducing the values ​​of the numerators and denominators of fractions, subsequent calculations become easier to perform.
  • To reduce a fraction to the lowest terms equivalent divide its numerator and denominator by their greatest common factor, GCF.

  • To calculate the GCF, factor the numerator and denominator of the fraction into prime factors.
  • Then multiply all the common prime factors: if there are repeating prime factors we only take them once, and only the ones having the lowest exponents (the lowest powers).

Reduce (simplify) the end fraction to its lowest terms equivalent:

Calculate the greatest common factor, GCF,
of the numerator and denominator of the fraction:

  • To reduce a fraction to the lowest terms equivalent divide its numerator and denominator by their greatest common factor, GCF.

  • To calculate the GCF, factor the numerator and denominator of the fraction into prime factors.
  • Then multiply all the common prime factors: if there are repeating prime factors we only take them once, and only the ones having the lowest exponents (the lowest powers).
  • But the numerator and the denominator have no common prime factors:


GCF (5 × 13 × 19 × 53 × 89 × 3,011 × 3,631 × 74,093; 25 × 34 × 11 × 29 × 113 × 131 × 431) = 1



Divide the numerator and the denominator by their GCF:

The numerator and the denominator of the fraction are coprime numbers (they have no common prime factors, the GCF = 1). The end fraction can no longer be reduced, it already has the smallest possible numerator and denominator.

As a mixed number (also called a mixed fraction):

  • A mixed number: a whole number and a proper fraction, both having the same sign.
  • A proper fraction: the value of the numerator is smaller than the value of the denominator.
  • Divide the numerator by the denominator and write down the quotient and the remainder of the division, as shown below:

- 4,718,967,842,439,993,935 ÷ 5,275,367,136,864 = - 894,528 and the remainder = - 4,228,235,313,743 ⇒

- 894,528.8

As a percentage:

  • A percentage value p% is equal to the fraction: p/100, for any decimal number p. So, we need to change the form of the number calculated above, to show a denominator of 100.
  • To do that, multiply the number by the fraction 100/100.
  • The value of the fraction 100/100 = 1, so by multiplying the number by this fraction the result is not changing, only the form.

- 894,528.801505412618 =


- 894,528.801505412618 × 100/100 =


( - 894,528.801505412618 × 100)/100 =
