Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
136,549,863/300,000,000,012
- The integer number above the bar is called numerator: 136,549,863
- The integer number below the bar is called denominator: 300,000,000,012
- 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 = 136,549,863 ÷ 300,000,000,012
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:
136,549,863 = 3 × 3 × 263 × 57,689 = 32 × 263 × 57,689
136,549,863 is a composite number.
Written with exponents:
300,000,000,012 = 2 × 2 × 3 × 17,573 × 1,422,637 = 22 × 3 × 17,573 × 1,422,637
300,000,000,012 is a composite number.
136,549,863/300,000,000,012 =
(136,549,863 ÷ 3) / (300,000,000,012 ÷ 3) =
45,516,621/100,000,000,004
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.
136,549,863/300,000,000,012 =
(32 × 263 × 57,689)/(22 × 3 × 17,573 × 1,422,637) =
((32 × 263 × 57,689) ÷ 3) / ((22 × 3 × 17,573 × 1,422,637) ÷ 3) =
(3 × 263 × 57,689)/(22 × 17,573 × 1,422,637) =
45,516,621/100,000,000,004
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
45,516,621/100,000,000,004 =
45,516,621 ÷ 100,000,000,004 =
0.00045516621 ≈
