Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
89,393,939,451/150,000,000,039
- The integer number above the bar is called numerator: 89,393,939,451
- The integer number below the bar is called denominator: 150,000,000,039
- 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 = 89,393,939,451 ÷ 150,000,000,039
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:
89,393,939,451 = 3 × 3 × 9,932,659,939 = 32 × 9,932,659,939
89,393,939,451 is a composite number.
Written with exponents:
150,000,000,039 = 3 × 3 × 3 × 5,555,555,557 = 33 × 5,555,555,557
150,000,000,039 is a composite number.
89,393,939,451/150,000,000,039 =
(89,393,939,451 ÷ 9) / (150,000,000,039 ÷ 9) =
9,932,659,939/16,666,666,671
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.
89,393,939,451/150,000,000,039 =
(32 × 9,932,659,939)/(33 × 5,555,555,557) =
((32 × 9,932,659,939) ÷ 32) / ((33 × 5,555,555,557) ÷ 32) =
9,932,659,939/(3 × 5,555,555,557) =
9,932,659,939/16,666,666,671
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
9,932,659,939/16,666,666,671 =
9,932,659,939 ÷ 16,666,666,671 =
