Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
41,666,666,679/75,000,000,009
- The integer number above the bar is called numerator: 41,666,666,679
- 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 = 41,666,666,679 ÷ 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:
41,666,666,679 = 3 × 3 × 3 × 11 × 140,291,807 = 33 × 11 × 140,291,807
41,666,666,679 is a composite number.
75,000,000,009 = 3 × 11 × 31 × 73,313,783
75,000,000,009 is a composite number.
41,666,666,679/75,000,000,009 =
(41,666,666,679 ÷ 33) / (75,000,000,009 ÷ 33) =
1,262,626,263/2,272,727,273
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.
41,666,666,679/75,000,000,009 =
(33 × 11 × 140,291,807)/(3 × 11 × 31 × 73,313,783) =
((33 × 11 × 140,291,807) ÷ (3 × 11)) / ((3 × 11 × 31 × 73,313,783) ÷ (3 × 11)) =
(32 × 140,291,807)/(31 × 73,313,783) =
1,262,626,263/2,272,727,273
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
1,262,626,263/2,272,727,273 =
1,262,626,263 ÷ 2,272,727,273 =
