Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
526,315,802/30,000,000,004
- The integer number above the bar is called numerator: 526,315,802
- The integer number below the bar is called denominator: 30,000,000,004
- 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 = 526,315,802 ÷ 30,000,000,004
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:
526,315,802 = 2 × 263,157,901
526,315,802 is a composite number.
Written with exponents:
30,000,000,004 = 2 × 2 × 13 × 223 × 2,587,099 = 22 × 13 × 223 × 2,587,099
30,000,000,004 is a composite number.
526,315,802/30,000,000,004 =
(526,315,802 ÷ 2) / (30,000,000,004 ÷ 2) =
263,157,901/15,000,000,002
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.
526,315,802/30,000,000,004 =
(2 × 263,157,901)/(22 × 13 × 223 × 2,587,099) =
((2 × 263,157,901) ÷ 2) / ((22 × 13 × 223 × 2,587,099) ÷ 2) =
263,157,901/(2 × 13 × 223 × 2,587,099) =
263,157,901/15,000,000,002
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
263,157,901/15,000,000,002 =
263,157,901 ÷ 15,000,000,002 =
