Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
33,333,333,370/60,000,000,050
- The integer number above the bar is called numerator: 33,333,333,370
- The integer number below the bar is called denominator: 60,000,000,050
- 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 = 33,333,333,370 ÷ 60,000,000,050
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:
33,333,333,370 = 2 × 5 × 191 × 17,452,007
33,333,333,370 is a composite number.
Written with exponents:
60,000,000,050 = 2 × 5 × 5 × 907 × 1,323,043 = 2 × 52 × 907 × 1,323,043
60,000,000,050 is a composite number.
33,333,333,370/60,000,000,050 =
(33,333,333,370 ÷ 10) / (60,000,000,050 ÷ 10) =
3,333,333,337/6,000,000,005
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.
33,333,333,370/60,000,000,050 =
(2 × 5 × 191 × 17,452,007)/(2 × 52 × 907 × 1,323,043) =
((2 × 5 × 191 × 17,452,007) ÷ (2 × 5)) / ((2 × 52 × 907 × 1,323,043) ÷ (2 × 5)) =
(191 × 17,452,007)/(5 × 907 × 1,323,043) =
3,333,333,337/6,000,000,005
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
3,333,333,337/6,000,000,005 =
3,333,333,337 ÷ 6,000,000,005 =
