Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
526,315,783/30,000,000,002
- The integer number above the bar is called numerator: 526,315,783
- The integer number below the bar is called denominator: 30,000,000,002
- 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 = 526,315,783 ÷ 30,000,000,002
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:
526,315,783 = 7 × 439 × 171,271
526,315,783 is a composite number.
Written with exponents:
30,000,000,002 = 2 × 7 × 7 × 306,122,449 = 2 × 72 × 306,122,449
30,000,000,002 is a composite number.
526,315,783/30,000,000,002 =
(526,315,783 ÷ 7) / (30,000,000,002 ÷ 7) =
75,187,969/4,285,714,286
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.
526,315,783/30,000,000,002 =
(7 × 439 × 171,271)/(2 × 72 × 306,122,449) =
((7 × 439 × 171,271) ÷ 7) / ((2 × 72 × 306,122,449) ÷ 7) =
(439 × 171,271)/(2 × 7 × 306,122,449) =
75,187,969/4,285,714,286
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
75,187,969/4,285,714,286 =
75,187,969 ÷ 4,285,714,286 =
