Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
89,393,939,510/150,000,000,095
- The integer number above the bar is called numerator: 89,393,939,510
- The integer number below the bar is called denominator: 150,000,000,095
- 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 = 89,393,939,510 ÷ 150,000,000,095
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:
89,393,939,510 = 2 × 5 × 17 × 17 × 101 × 306,259 = 2 × 5 × 172 × 101 × 306,259
89,393,939,510 is a composite number.
150,000,000,095 = 5 × 11 × 61 × 44,709,389
150,000,000,095 is a composite number.
89,393,939,510/150,000,000,095 =
(89,393,939,510 ÷ 5) / (150,000,000,095 ÷ 5) =
17,878,787,902/30,000,000,019
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.
89,393,939,510/150,000,000,095 =
(2 × 5 × 172 × 101 × 306,259)/(5 × 11 × 61 × 44,709,389) =
((2 × 5 × 172 × 101 × 306,259) ÷ 5) / ((5 × 11 × 61 × 44,709,389) ÷ 5) =
(2 × 172 × 101 × 306,259)/(11 × 61 × 44,709,389) =
17,878,787,902/30,000,000,019
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
17,878,787,902/30,000,000,019 =
17,878,787,902 ÷ 30,000,000,019 =
