Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
10,666,666,598/19,999,999,915
- The integer number above the bar is called numerator: 10,666,666,598
- The integer number below the bar is called denominator: 19,999,999,915
- 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 = 10,666,666,598 ÷ 19,999,999,915
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:
10,666,666,598 = 2 × 7 × 761,904,757
10,666,666,598 is a composite number.
19,999,999,915 = 5 × 7 × 571,428,569
19,999,999,915 is a composite number.
10,666,666,598/19,999,999,915 =
(10,666,666,598 ÷ 7) / (19,999,999,915 ÷ 7) =
1,523,809,514/2,857,142,845
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.
10,666,666,598/19,999,999,915 =
(2 × 7 × 761,904,757)/(5 × 7 × 571,428,569) =
((2 × 7 × 761,904,757) ÷ 7) / ((5 × 7 × 571,428,569) ÷ 7) =
(2 × 761,904,757)/(5 × 571,428,569) =
1,523,809,514/2,857,142,845
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
1,523,809,514/2,857,142,845 =
1,523,809,514 ÷ 2,857,142,845 =
