Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
33,333,333,378/60,000,000,080
- The integer number above the bar is called numerator: 33,333,333,378
- The integer number below the bar is called denominator: 60,000,000,080
- 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 = 33,333,333,378 ÷ 60,000,000,080
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:
33,333,333,378 = 2 × 3 × 5,555,555,563
33,333,333,378 is a composite number.
Written with exponents:
60,000,000,080 = 2 × 2 × 2 × 2 × 5 × 29 × 163 × 158,663 = 24 × 5 × 29 × 163 × 158,663
60,000,000,080 is a composite number.
33,333,333,378/60,000,000,080 =
(33,333,333,378 ÷ 2) / (60,000,000,080 ÷ 2) =
16,666,666,689/30,000,000,040
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.
33,333,333,378/60,000,000,080 =
(2 × 3 × 5,555,555,563)/(24 × 5 × 29 × 163 × 158,663) =
((2 × 3 × 5,555,555,563) ÷ 2) / ((24 × 5 × 29 × 163 × 158,663) ÷ 2) =
(3 × 5,555,555,563)/(23 × 5 × 29 × 163 × 158,663) =
16,666,666,689/30,000,000,040
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
16,666,666,689/30,000,000,040 =
16,666,666,689 ÷ 30,000,000,040 =
0.555555555559 ≈
