Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
89,393,939,478/150,000,000,012
- The integer number above the bar is called numerator: 89,393,939,478
- The integer number below the bar is called denominator: 150,000,000,012
- 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 = 89,393,939,478 ÷ 150,000,000,012
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:
89,393,939,478 = 2 × 3 × 3 × 2,141 × 2,319,631 = 2 × 32 × 2,141 × 2,319,631
89,393,939,478 is a composite number.
Written with exponents:
150,000,000,012 = 2 × 2 × 3 × 3 × 3 × 3 × 462,962,963 = 22 × 34 × 462,962,963
150,000,000,012 is a composite number.
89,393,939,478/150,000,000,012 =
(89,393,939,478 ÷ 18) / (150,000,000,012 ÷ 18) =
4,966,329,971/8,333,333,334
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.
89,393,939,478/150,000,000,012 =
(2 × 32 × 2,141 × 2,319,631)/(22 × 34 × 462,962,963) =
((2 × 32 × 2,141 × 2,319,631) ÷ (2 × 32)) / ((22 × 34 × 462,962,963) ÷ (2 × 32)) =
(2,141 × 2,319,631)/(2 × 32 × 462,962,963) =
4,966,329,971/8,333,333,334
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
4,966,329,971/8,333,333,334 =
4,966,329,971 ÷ 8,333,333,334 =
0.595959596472 ≈
