Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
779,422,863,388/900,000,000,003
- The integer number above the bar is called numerator: 779,422,863,388
- The integer number below the bar is called denominator: 900,000,000,003
- 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 = 779,422,863,388 ÷ 900,000,000,003
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:
779,422,863,388 = 2 × 2 × 13 × 953 × 15,728,123 = 22 × 13 × 953 × 15,728,123
779,422,863,388 is a composite number.
Written with exponents:
900,000,000,003 = 3 × 13 × 13 × 1,775,147,929 = 3 × 132 × 1,775,147,929
900,000,000,003 is a composite number.
779,422,863,388/900,000,000,003 =
(779,422,863,388 ÷ 13) / (900,000,000,003 ÷ 13) =
59,955,604,876/69,230,769,231
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.
779,422,863,388/900,000,000,003 =
(22 × 13 × 953 × 15,728,123)/(3 × 132 × 1,775,147,929) =
((22 × 13 × 953 × 15,728,123) ÷ 13) / ((3 × 132 × 1,775,147,929) ÷ 13) =
(22 × 953 × 15,728,123)/(3 × 13 × 1,775,147,929) =
59,955,604,876/69,230,769,231
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
59,955,604,876/69,230,769,231 =
59,955,604,876 ÷ 69,230,769,231 =
0.866025403762 ≈
