Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
779,422,863,399/899,999,999,952
- The integer number above the bar is called numerator: 779,422,863,399
- The integer number below the bar is called denominator: 899,999,999,952
- 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 = 779,422,863,399 ÷ 899,999,999,952
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:
779,422,863,399 = 3 × 259,807,621,133
779,422,863,399 is a composite number.
Written with exponents:
899,999,999,952 = 2 × 2 × 2 × 2 × 3 × 233 × 80,472,103 = 24 × 3 × 233 × 80,472,103
899,999,999,952 is a composite number.
779,422,863,399/899,999,999,952 =
(779,422,863,399 ÷ 3) / (899,999,999,952 ÷ 3) =
259,807,621,133/299,999,999,984
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.
779,422,863,399/899,999,999,952 =
(3 × 259,807,621,133)/(24 × 3 × 233 × 80,472,103) =
((3 × 259,807,621,133) ÷ 3) / ((24 × 3 × 233 × 80,472,103) ÷ 3) =
259,807,621,133/(24 × 233 × 80,472,103) =
259,807,621,133/299,999,999,984
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
259,807,621,133/299,999,999,984 =
259,807,621,133 ÷ 299,999,999,984 =
