Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
33,333,333,332/60,000,000,028
- The integer number above the bar is called numerator: 33,333,333,332
- The integer number below the bar is called denominator: 60,000,000,028
- 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 = 33,333,333,332 ÷ 60,000,000,028
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:
33,333,333,332 = 2 × 2 × 13 × 7,477 × 85,733 = 22 × 13 × 7,477 × 85,733
33,333,333,332 is a composite number.
Written with exponents:
60,000,000,028 = 2 × 2 × 15,000,000,007 = 22 × 15,000,000,007
60,000,000,028 is a composite number.
33,333,333,332/60,000,000,028 =
(33,333,333,332 ÷ 4) / (60,000,000,028 ÷ 4) =
8,333,333,333/15,000,000,007
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.
33,333,333,332/60,000,000,028 =
(22 × 13 × 7,477 × 85,733)/(22 × 15,000,000,007) =
((22 × 13 × 7,477 × 85,733) ÷ 22) / ((22 × 15,000,000,007) ÷ 22) =
(13 × 7,477 × 85,733)/15,000,000,007 =
8,333,333,333/15,000,000,007
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
8,333,333,333/15,000,000,007 =
8,333,333,333 ÷ 15,000,000,007 =
