Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
16,666,666,647/29,999,999,955
- The integer number above the bar is called numerator: 16,666,666,647
- The integer number below the bar is called denominator: 29,999,999,955
- 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 = 16,666,666,647 ÷ 29,999,999,955
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:
16,666,666,647 = 3 × 29 × 191,570,881
16,666,666,647 is a composite number.
29,999,999,955 = 3 × 5 × 53 × 37,735,849
29,999,999,955 is a composite number.
16,666,666,647/29,999,999,955 =
(16,666,666,647 ÷ 3) / (29,999,999,955 ÷ 3) =
5,555,555,549/9,999,999,985
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.
16,666,666,647/29,999,999,955 =
(3 × 29 × 191,570,881)/(3 × 5 × 53 × 37,735,849) =
((3 × 29 × 191,570,881) ÷ 3) / ((3 × 5 × 53 × 37,735,849) ÷ 3) =
(29 × 191,570,881)/(5 × 53 × 37,735,849) =
5,555,555,549/9,999,999,985
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
5,555,555,549/9,999,999,985 =
5,555,555,549 ÷ 9,999,999,985 =
0.555555555733 ≈
