Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
89,393,939,484/150,000,000,090
- The integer number above the bar is called numerator: 89,393,939,484
- The integer number below the bar is called denominator: 150,000,000,090
- 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 = 89,393,939,484 ÷ 150,000,000,090
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:
89,393,939,484 = 2 × 2 × 3 × 641 × 11,621,677 = 22 × 3 × 641 × 11,621,677
89,393,939,484 is a composite number.
150,000,000,090 = 2 × 3 × 5 × 149 × 33,557,047
150,000,000,090 is a composite number.
89,393,939,484/150,000,000,090 =
(89,393,939,484 ÷ 6) / (150,000,000,090 ÷ 6) =
14,898,989,914/25,000,000,015
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.
89,393,939,484/150,000,000,090 =
(22 × 3 × 641 × 11,621,677)/(2 × 3 × 5 × 149 × 33,557,047) =
((22 × 3 × 641 × 11,621,677) ÷ (2 × 3)) / ((2 × 3 × 5 × 149 × 33,557,047) ÷ (2 × 3)) =
(2 × 641 × 11,621,677)/(5 × 149 × 33,557,047) =
14,898,989,914/25,000,000,015
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
14,898,989,914/25,000,000,015 =
14,898,989,914 ÷ 25,000,000,015 =
