Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
89,393,939,452/150,000,000,016
- The integer number above the bar is called numerator: 89,393,939,452
- The integer number below the bar is called denominator: 150,000,000,016
- 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 = 89,393,939,452 ÷ 150,000,000,016
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:
89,393,939,452 = 2 × 2 × 5,669 × 3,942,227 = 22 × 5,669 × 3,942,227
89,393,939,452 is a composite number.
Written with exponents:
150,000,000,016 = 2 × 2 × 2 × 2 × 9,375,000,001 = 24 × 9,375,000,001
150,000,000,016 is a composite number.
89,393,939,452/150,000,000,016 =
(89,393,939,452 ÷ 4) / (150,000,000,016 ÷ 4) =
22,348,484,863/37,500,000,004
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.
89,393,939,452/150,000,000,016 =
(22 × 5,669 × 3,942,227)/(24 × 9,375,000,001) =
((22 × 5,669 × 3,942,227) ÷ 22) / ((24 × 9,375,000,001) ÷ 22) =
(5,669 × 3,942,227)/(22 × 9,375,000,001) =
22,348,484,863/37,500,000,004
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
22,348,484,863/37,500,000,004 =
22,348,484,863 ÷ 37,500,000,004 =
