Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
33,333,333,285/60,000,000,067
- The integer number above the bar is called numerator: 33,333,333,285
- The integer number below the bar is called denominator: 60,000,000,067
- 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 = 33,333,333,285 ÷ 60,000,000,067
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:
33,333,333,285 = 3 × 5 × 7 × 103 × 3,082,139
33,333,333,285 is a composite number.
60,000,000,067 = 7 × 7,253 × 1,181,777
60,000,000,067 is a composite number.
33,333,333,285/60,000,000,067 =
(33,333,333,285 ÷ 7) / (60,000,000,067 ÷ 7) =
4,761,904,755/8,571,428,581
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.
33,333,333,285/60,000,000,067 =
(3 × 5 × 7 × 103 × 3,082,139)/(7 × 7,253 × 1,181,777) =
((3 × 5 × 7 × 103 × 3,082,139) ÷ 7) / ((7 × 7,253 × 1,181,777) ÷ 7) =
(3 × 5 × 103 × 3,082,139)/(7,253 × 1,181,777) =
4,761,904,755/8,571,428,581
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
4,761,904,755/8,571,428,581 =
4,761,904,755 ÷ 8,571,428,581 =
0.55555555413 ≈
