Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
16,666,666,760/30,000,000,055
- The integer number above the bar is called numerator: 16,666,666,760
- The integer number below the bar is called denominator: 30,000,000,055
- 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 = 16,666,666,760 ÷ 30,000,000,055
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:
16,666,666,760 = 2 × 2 × 2 × 5 × 401 × 1,039,069 = 23 × 5 × 401 × 1,039,069
16,666,666,760 is a composite number.
30,000,000,055 = 5 × 883 × 1,759 × 3,863
30,000,000,055 is a composite number.
16,666,666,760/30,000,000,055 =
(16,666,666,760 ÷ 5) / (30,000,000,055 ÷ 5) =
3,333,333,352/6,000,000,011
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.
16,666,666,760/30,000,000,055 =
(23 × 5 × 401 × 1,039,069)/(5 × 883 × 1,759 × 3,863) =
((23 × 5 × 401 × 1,039,069) ÷ 5) / ((5 × 883 × 1,759 × 3,863) ÷ 5) =
(23 × 401 × 1,039,069)/(883 × 1,759 × 3,863) =
3,333,333,352/6,000,000,011
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
3,333,333,352/6,000,000,011 =
3,333,333,352 ÷ 6,000,000,011 =
