Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
16,666,666,688/29,999,999,954
- The integer number above the bar is called numerator: 16,666,666,688
- The integer number below the bar is called denominator: 29,999,999,954
- 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 = 16,666,666,688 ÷ 29,999,999,954
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:
Written with exponents:
16,666,666,688 = 2 × 2 × 2 × 2 × 2 × 2 × 7 × 5,843 × 6,367 = 26 × 7 × 5,843 × 6,367
16,666,666,688 is a composite number.
29,999,999,954 = 2 × 19 × 31 × 25,466,893
29,999,999,954 is a composite number.
16,666,666,688/29,999,999,954 =
(16,666,666,688 ÷ 2) / (29,999,999,954 ÷ 2) =
8,333,333,344/14,999,999,977
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.
16,666,666,688/29,999,999,954 =
(26 × 7 × 5,843 × 6,367)/(2 × 19 × 31 × 25,466,893) =
((26 × 7 × 5,843 × 6,367) ÷ 2) / ((2 × 19 × 31 × 25,466,893) ÷ 2) =
(25 × 7 × 5,843 × 6,367)/(19 × 31 × 25,466,893) =
8,333,333,344/14,999,999,977
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
8,333,333,344/14,999,999,977 =
8,333,333,344 ÷ 14,999,999,977 =
