Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
41,666,666,658/75,000,000,000
- The integer number above the bar is called numerator: 41,666,666,658
- The integer number below the bar is called denominator: 75,000,000,000
- 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 = 41,666,666,658 ÷ 75,000,000,000
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:
41,666,666,658 = 2 × 3 × 57,131 × 121,553
41,666,666,658 is a composite number.
Written with exponents:
75,000,000,000 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 3 × 5 × 5 × 5 × 5 × 5 × 5 × 5 × 5 × 5 × 5 × 5 = 29 × 3 × 511
75,000,000,000 is a composite number.
41,666,666,658/75,000,000,000 =
(41,666,666,658 ÷ 6) / (75,000,000,000 ÷ 6) =
6,944,444,443/12,500,000,000
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.
41,666,666,658/75,000,000,000 =
(2 × 3 × 57,131 × 121,553)/(29 × 3 × 511) =
((2 × 3 × 57,131 × 121,553) ÷ (2 × 3)) / ((29 × 3 × 511) ÷ (2 × 3)) =
(57,131 × 121,553)/(28 × 511) =
6,944,444,443/12,500,000,000
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
6,944,444,443/12,500,000,000 =
6,944,444,443 ÷ 12,500,000,000 =
