Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
68,274,928/150,000,000,010
- The integer number above the bar is called numerator: 68,274,928
- The integer number below the bar is called denominator: 150,000,000,010
- 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 = 68,274,928 ÷ 150,000,000,010
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:
68,274,928 = 2 × 2 × 2 × 2 × 4,267,183 = 24 × 4,267,183
68,274,928 is a composite number.
Written with exponents:
150,000,000,010 = 2 × 5 × 7 × 7 × 306,122,449 = 2 × 5 × 72 × 306,122,449
150,000,000,010 is a composite number.
68,274,928/150,000,000,010 =
(68,274,928 ÷ 2) / (150,000,000,010 ÷ 2) =
34,137,464/75,000,000,005
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.
68,274,928/150,000,000,010 =
(24 × 4,267,183)/(2 × 5 × 72 × 306,122,449) =
((24 × 4,267,183) ÷ 2) / ((2 × 5 × 72 × 306,122,449) ÷ 2) =
(23 × 4,267,183)/(5 × 72 × 306,122,449) =
34,137,464/75,000,000,005
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
34,137,464/75,000,000,005 =
34,137,464 ÷ 75,000,000,005 =
