Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
1,010,101,029/3,999,999,996
- The integer number above the bar is called numerator: 1,010,101,029
- The integer number below the bar is called denominator: 3,999,999,996
- 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 = 1,010,101,029 ÷ 3,999,999,996
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:
1,010,101,029 = 3 × 7 × 48,100,049
1,010,101,029 is a composite number.
Written with exponents:
3,999,999,996 = 2 × 2 × 3 × 3 × 3 × 3 × 37 × 333,667 = 22 × 34 × 37 × 333,667
3,999,999,996 is a composite number.
1,010,101,029/3,999,999,996 =
(1,010,101,029 ÷ 3) / (3,999,999,996 ÷ 3) =
336,700,343/1,333,333,332
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.
1,010,101,029/3,999,999,996 =
(3 × 7 × 48,100,049)/(22 × 34 × 37 × 333,667) =
((3 × 7 × 48,100,049) ÷ 3) / ((22 × 34 × 37 × 333,667) ÷ 3) =
(7 × 48,100,049)/(22 × 33 × 37 × 333,667) =
336,700,343/1,333,333,332
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
336,700,343/1,333,333,332 =
336,700,343 ÷ 1,333,333,332 =
