Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
89,393,939,350/149,999,999,970
- The integer number above the bar is called numerator: 89,393,939,350
- The integer number below the bar is called denominator: 149,999,999,970
- 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 = 89,393,939,350 ÷ 149,999,999,970
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:
89,393,939,350 = 2 × 5 × 5 × 167 × 10,705,861 = 2 × 52 × 167 × 10,705,861
89,393,939,350 is a composite number.
149,999,999,970 = 2 × 3 × 5 × 17 × 14,033 × 20,959
149,999,999,970 is a composite number.
89,393,939,350/149,999,999,970 =
(89,393,939,350 ÷ 10) / (149,999,999,970 ÷ 10) =
8,939,393,935/14,999,999,997
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.
89,393,939,350/149,999,999,970 =
(2 × 52 × 167 × 10,705,861)/(2 × 3 × 5 × 17 × 14,033 × 20,959) =
((2 × 52 × 167 × 10,705,861) ÷ (2 × 5)) / ((2 × 3 × 5 × 17 × 14,033 × 20,959) ÷ (2 × 5)) =
(5 × 167 × 10,705,861)/(3 × 17 × 14,033 × 20,959) =
8,939,393,935/14,999,999,997
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
8,939,393,935/14,999,999,997 =
8,939,393,935 ÷ 14,999,999,997 =
0.595959595786 ≈
