Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
16,666,666,731/30,000,000,057
- The integer number above the bar is called numerator: 16,666,666,731
- The integer number below the bar is called denominator: 30,000,000,057
- 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 = 16,666,666,731 ÷ 30,000,000,057
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:
16,666,666,731 = 3 × 3 × 3 × 11 × 13 × 631 × 6,841 = 33 × 11 × 13 × 631 × 6,841
16,666,666,731 is a composite number.
30,000,000,057 = 3 × 10,000,000,019
30,000,000,057 is a composite number.
16,666,666,731/30,000,000,057 =
(16,666,666,731 ÷ 3) / (30,000,000,057 ÷ 3) =
5,555,555,577/10,000,000,019
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.
16,666,666,731/30,000,000,057 =
(33 × 11 × 13 × 631 × 6,841)/(3 × 10,000,000,019) =
((33 × 11 × 13 × 631 × 6,841) ÷ 3) / ((3 × 10,000,000,019) ÷ 3) =
(32 × 11 × 13 × 631 × 6,841)/10,000,000,019 =
5,555,555,577/10,000,000,019
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
5,555,555,577/10,000,000,019 =
5,555,555,577 ÷ 10,000,000,019 =
0.555555556644 ≈
