Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
1,010,101,035/4,000,000,017
- The integer number above the bar is called numerator: 1,010,101,035
- The integer number below the bar is called denominator: 4,000,000,017
- 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 = 1,010,101,035 ÷ 4,000,000,017
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:
1,010,101,035 = 3 × 5 × 67,340,069
1,010,101,035 is a composite number.
4,000,000,017 = 3 × 13 × 102,564,103
4,000,000,017 is a composite number.
1,010,101,035/4,000,000,017 =
(1,010,101,035 ÷ 3) / (4,000,000,017 ÷ 3) =
336,700,345/1,333,333,339
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.
1,010,101,035/4,000,000,017 =
(3 × 5 × 67,340,069)/(3 × 13 × 102,564,103) =
((3 × 5 × 67,340,069) ÷ 3) / ((3 × 13 × 102,564,103) ÷ 3) =
(5 × 67,340,069)/(13 × 102,564,103) =
336,700,345/1,333,333,339
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
336,700,345/1,333,333,339 =
336,700,345 ÷ 1,333,333,339 =
