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).

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.
