Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
779,422,863,424/900,000,000,096
- The integer number above the bar is called numerator: 779,422,863,424
- The integer number below the bar is called denominator: 900,000,000,096
- 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 = 779,422,863,424 ÷ 900,000,000,096
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:
779,422,863,424 = 2 × 2 × 2 × 2 × 2 × 2 × 12,178,482,241 = 26 × 12,178,482,241
779,422,863,424 is a composite number.
Written with exponents:
900,000,000,096 = 2 × 2 × 2 × 2 × 2 × 3 × 9,375,000,001 = 25 × 3 × 9,375,000,001
900,000,000,096 is a composite number.
779,422,863,424/900,000,000,096 =
(779,422,863,424 ÷ 32) / (900,000,000,096 ÷ 32) =
24,356,964,482/28,125,000,003
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.
779,422,863,424/900,000,000,096 =
(26 × 12,178,482,241)/(25 × 3 × 9,375,000,001) =
((26 × 12,178,482,241) ÷ 25) / ((25 × 3 × 9,375,000,001) ÷ 25) =
(2 × 12,178,482,241)/(3 × 9,375,000,001) =
24,356,964,482/28,125,000,003
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
24,356,964,482/28,125,000,003 =
24,356,964,482 ÷ 28,125,000,003 =
