Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
16,666,666,705/29,999,999,978
- The integer number above the bar is called numerator: 16,666,666,705
- The integer number below the bar is called denominator: 29,999,999,978
- 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 = 16,666,666,705 ÷ 29,999,999,978
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:
16,666,666,705 = 5 × 13 × 29 × 8,841,733
16,666,666,705 is a composite number.
29,999,999,978 = 2 × 13 × 11,447 × 100,799
29,999,999,978 is a composite number.
16,666,666,705/29,999,999,978 =
(16,666,666,705 ÷ 13) / (29,999,999,978 ÷ 13) =
1,282,051,285/2,307,692,306
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.
16,666,666,705/29,999,999,978 =
(5 × 13 × 29 × 8,841,733)/(2 × 13 × 11,447 × 100,799) =
((5 × 13 × 29 × 8,841,733) ÷ 13) / ((2 × 13 × 11,447 × 100,799) ÷ 13) =
(5 × 29 × 8,841,733)/(2 × 11,447 × 100,799) =
1,282,051,285/2,307,692,306
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
1,282,051,285/2,307,692,306 =
1,282,051,285 ÷ 2,307,692,306 =
0.555555557241 ≈
