Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
16,666,666,736/29,999,999,986
- The integer number above the bar is called numerator: 16,666,666,736
- The integer number below the bar is called denominator: 29,999,999,986
- 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 = 16,666,666,736 ÷ 29,999,999,986
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:
16,666,666,736 = 2 × 2 × 2 × 2 × 2,843 × 366,397 = 24 × 2,843 × 366,397
16,666,666,736 is a composite number.
29,999,999,986 = 2 × 11 × 1,363,636,363
29,999,999,986 is a composite number.
16,666,666,736/29,999,999,986 =
(16,666,666,736 ÷ 2) / (29,999,999,986 ÷ 2) =
8,333,333,368/14,999,999,993
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.
16,666,666,736/29,999,999,986 =
(24 × 2,843 × 366,397)/(2 × 11 × 1,363,636,363) =
((24 × 2,843 × 366,397) ÷ 2) / ((2 × 11 × 1,363,636,363) ÷ 2) =
(23 × 2,843 × 366,397)/(11 × 1,363,636,363) =
8,333,333,368/14,999,999,993
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
8,333,333,368/14,999,999,993 =
8,333,333,368 ÷ 14,999,999,993 =
