Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
89,393,939,469/150,000,000,057
- The integer number above the bar is called numerator: 89,393,939,469
- The integer number below the bar is called denominator: 150,000,000,057
- 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 = 89,393,939,469 ÷ 150,000,000,057
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:
89,393,939,469 = 3 × 3 × 3 × 3,310,886,647 = 33 × 3,310,886,647
89,393,939,469 is a composite number.
Written with exponents:
150,000,000,057 = 3 × 3 × 67 × 239 × 1,040,821 = 32 × 67 × 239 × 1,040,821
150,000,000,057 is a composite number.
89,393,939,469/150,000,000,057 =
(89,393,939,469 ÷ 9) / (150,000,000,057 ÷ 9) =
9,932,659,941/16,666,666,673
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.
89,393,939,469/150,000,000,057 =
(33 × 3,310,886,647)/(32 × 67 × 239 × 1,040,821) =
((33 × 3,310,886,647) ÷ 32) / ((32 × 67 × 239 × 1,040,821) ÷ 32) =
(3 × 3,310,886,647)/(67 × 239 × 1,040,821) =
9,932,659,941/16,666,666,673
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
9,932,659,941/16,666,666,673 =
9,932,659,941 ÷ 16,666,666,673 =
