Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
506,070,633/12,499,999,989
- The integer number above the bar is called numerator: 506,070,633
- The integer number below the bar is called denominator: 12,499,999,989
- The fraction bar means that the numerator is divided by the denominator.
- To get the fraction's value divide the numerator by the denominator:
The value = 506,070,633 ÷ 12,499,999,989
To reduce a fraction to the lowest terms equivalent: divide the numerator and denominator by their greatest common factor, GCF
To calculate the greatest common factor, GCF:
- 1. Factor the numerator and the denominator (into prime factors), build their prime factorizations.
- 2. Multiply all their common prime factors, taken by the lowest exponents.
1. Factor the numerator and the denominator:
To factor a number (into prime factors) - or, in other words, to break it down to prime factors - or, in other words, to build its prime factorization: find the prime numbers that multiply together to get that number.
The prime factorizations:
506,070,633 = 3 × 23 × 7,334,357
506,070,633 is a composite number.
12,499,999,989 = 3 × 17 × 245,098,039
12,499,999,989 is a composite number.
506,070,633/12,499,999,989 =
(506,070,633 ÷ 3) / (12,499,999,989 ÷ 3) =
168,690,211/4,166,666,663
Yet another method to reduce the 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.
506,070,633/12,499,999,989 =
(3 × 23 × 7,334,357)/(3 × 17 × 245,098,039) =
((3 × 23 × 7,334,357) ÷ 3) / ((3 × 17 × 245,098,039) ÷ 3) =
(23 × 7,334,357)/(17 × 245,098,039) =
168,690,211/4,166,666,663
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
168,690,211/4,166,666,663 =
168,690,211 ÷ 4,166,666,663 =
