Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
33,333,333,439/60,000,000,074
- The integer number above the bar is called numerator: 33,333,333,439
- The integer number below the bar is called denominator: 60,000,000,074
- 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 = 33,333,333,439 ÷ 60,000,000,074
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:
33,333,333,439 = 7 × 7 × 29 × 23,457,659 = 72 × 29 × 23,457,659
33,333,333,439 is a composite number.
60,000,000,074 = 2 × 7 × 4,285,714,291
60,000,000,074 is a composite number.
33,333,333,439/60,000,000,074 =
(33,333,333,439 ÷ 7) / (60,000,000,074 ÷ 7) =
4,761,904,777/8,571,428,582
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.
33,333,333,439/60,000,000,074 =
(72 × 29 × 23,457,659)/(2 × 7 × 4,285,714,291) =
((72 × 29 × 23,457,659) ÷ 7) / ((2 × 7 × 4,285,714,291) ÷ 7) =
(7 × 29 × 23,457,659)/(2 × 4,285,714,291) =
4,761,904,777/8,571,428,582
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
4,761,904,777/8,571,428,582 =
4,761,904,777 ÷ 8,571,428,582 =
