Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
89,393,939,480/150,000,000,055
- The integer number above the bar is called numerator: 89,393,939,480
- The integer number below the bar is called denominator: 150,000,000,055
- 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 = 89,393,939,480 ÷ 150,000,000,055
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:
89,393,939,480 = 2 × 2 × 2 × 5 × 2,234,848,487 = 23 × 5 × 2,234,848,487
89,393,939,480 is a composite number.
150,000,000,055 = 5 × 17 × 19 × 29 × 3,202,733
150,000,000,055 is a composite number.
89,393,939,480/150,000,000,055 =
(89,393,939,480 ÷ 5) / (150,000,000,055 ÷ 5) =
17,878,787,896/30,000,000,011
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.
89,393,939,480/150,000,000,055 =
(23 × 5 × 2,234,848,487)/(5 × 17 × 19 × 29 × 3,202,733) =
((23 × 5 × 2,234,848,487) ÷ 5) / ((5 × 17 × 19 × 29 × 3,202,733) ÷ 5) =
(23 × 2,234,848,487)/(17 × 19 × 29 × 3,202,733) =
17,878,787,896/30,000,000,011
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
17,878,787,896/30,000,000,011 =
17,878,787,896 ÷ 30,000,000,011 =
