Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
16,666,666,754/30,000,000,046
- The integer number above the bar is called numerator: 16,666,666,754
- The integer number below the bar is called denominator: 30,000,000,046
- 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 = 16,666,666,754 ÷ 30,000,000,046
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:
16,666,666,754 = 2 × 17 × 859 × 570,659
16,666,666,754 is a composite number.
30,000,000,046 = 2 × 281 × 5,641 × 9,463
30,000,000,046 is a composite number.
16,666,666,754/30,000,000,046 =
(16,666,666,754 ÷ 2) / (30,000,000,046 ÷ 2) =
8,333,333,377/15,000,000,023
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.
16,666,666,754/30,000,000,046 =
(2 × 17 × 859 × 570,659)/(2 × 281 × 5,641 × 9,463) =
((2 × 17 × 859 × 570,659) ÷ 2) / ((2 × 281 × 5,641 × 9,463) ÷ 2) =
(17 × 859 × 570,659)/(281 × 5,641 × 9,463) =
8,333,333,377/15,000,000,023
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
8,333,333,377/15,000,000,023 =
8,333,333,377 ÷ 15,000,000,023 =
