Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
41,666,666,661/75,000,000,009
- The integer number above the bar is called numerator: 41,666,666,661
- The integer number below the bar is called denominator: 75,000,000,009
- 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 = 41,666,666,661 ÷ 75,000,000,009
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:
41,666,666,661 = 3 × 3 × 29 × 137 × 1,165,273 = 32 × 29 × 137 × 1,165,273
41,666,666,661 is a composite number.
75,000,000,009 = 3 × 11 × 31 × 73,313,783
75,000,000,009 is a composite number.
41,666,666,661/75,000,000,009 =
(41,666,666,661 ÷ 3) / (75,000,000,009 ÷ 3) =
13,888,888,887/25,000,000,003
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.
41,666,666,661/75,000,000,009 =
(32 × 29 × 137 × 1,165,273)/(3 × 11 × 31 × 73,313,783) =
((32 × 29 × 137 × 1,165,273) ÷ 3) / ((3 × 11 × 31 × 73,313,783) ÷ 3) =
(3 × 29 × 137 × 1,165,273)/(11 × 31 × 73,313,783) =
13,888,888,887/25,000,000,003
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
13,888,888,887/25,000,000,003 =
13,888,888,887 ÷ 25,000,000,003 =
