Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
33,333,333,271/60,000,000,018
- The integer number above the bar is called numerator: 33,333,333,271
- The integer number below the bar is called denominator: 60,000,000,018
- 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 = 33,333,333,271 ÷ 60,000,000,018
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:
33,333,333,271 = 7 × 43 × 173 × 640,127
33,333,333,271 is a composite number.
60,000,000,018 = 2 × 3 × 7 × 1,428,571,429
60,000,000,018 is a composite number.
33,333,333,271/60,000,000,018 =
(33,333,333,271 ÷ 7) / (60,000,000,018 ÷ 7) =
4,761,904,753/8,571,428,574
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.
33,333,333,271/60,000,000,018 =
(7 × 43 × 173 × 640,127)/(2 × 3 × 7 × 1,428,571,429) =
((7 × 43 × 173 × 640,127) ÷ 7) / ((2 × 3 × 7 × 1,428,571,429) ÷ 7) =
(43 × 173 × 640,127)/(2 × 3 × 1,428,571,429) =
4,761,904,753/8,571,428,574
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
4,761,904,753/8,571,428,574 =
4,761,904,753 ÷ 8,571,428,574 =
0.55555555435 ≈
