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).
The fraction: 8,356/620
The prime factorizations of the numerator and denominator:
8,356 = 22 × 2,089
620 = 22 × 5 × 31

8,356/620 =
(8,356 ÷ 4)/(620 ÷ 4) =
2,089/155
Yet another method to reduce a fraction:
* To reduce a fraction without calculating the GCF: factor its numerator and denominator, then all the common prime factors are easily identified and crossed out.
8,356/620 =
(22 × 2,089)/(22 × 5 × 31) =
((22 × 2,089) ÷ 22)/((22 × 5 × 31) ÷ 22) =

Rewrite the fraction
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:
- 173,985,671,300,356,575 ÷ 20,670,246,464 = - 8,417,203 and the remainder = - 10,752,836,383 ⇒

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.
- 8,417,203.520208426239 =
- 8,417,203.520208426239 × 100/100 =
