Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
41,666,666,655/75,000,000,005
- The integer number above the bar is called numerator: 41,666,666,655
- The integer number below the bar is called denominator: 75,000,000,005
- 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 = 41,666,666,655 ÷ 75,000,000,005
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:
41,666,666,655 = 3 × 5 × 2,777,777,777
41,666,666,655 is a composite number.
Written with exponents:
75,000,000,005 = 5 × 7 × 7 × 306,122,449 = 5 × 72 × 306,122,449
75,000,000,005 is a composite number.
41,666,666,655/75,000,000,005 =
(41,666,666,655 ÷ 5) / (75,000,000,005 ÷ 5) =
8,333,333,331/15,000,000,001
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.
41,666,666,655/75,000,000,005 =
(3 × 5 × 2,777,777,777)/(5 × 72 × 306,122,449) =
((3 × 5 × 2,777,777,777) ÷ 5) / ((5 × 72 × 306,122,449) ÷ 5) =
(3 × 2,777,777,777)/(72 × 306,122,449) =
8,333,333,331/15,000,000,001
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
8,333,333,331/15,000,000,001 =
8,333,333,331 ÷ 15,000,000,001 =
