Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
124,999,999,992/225,000,000,002
- The integer number above the bar is called numerator: 124,999,999,992
- The integer number below the bar is called denominator: 225,000,000,002
- 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 = 124,999,999,992 ÷ 225,000,000,002
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:
124,999,999,992 = 2 × 2 × 2 × 3 × 3 × 7 × 7 × 17 × 19 × 43 × 2,551 = 23 × 32 × 72 × 17 × 19 × 43 × 2,551
124,999,999,992 is a composite number.
225,000,000,002 = 2 × 709 × 3,467 × 45,767
225,000,000,002 is a composite number.
124,999,999,992/225,000,000,002 =
(124,999,999,992 ÷ 2) / (225,000,000,002 ÷ 2) =
62,499,999,996/112,500,000,001
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.
124,999,999,992/225,000,000,002 =
(23 × 32 × 72 × 17 × 19 × 43 × 2,551)/(2 × 709 × 3,467 × 45,767) =
((23 × 32 × 72 × 17 × 19 × 43 × 2,551) ÷ 2) / ((2 × 709 × 3,467 × 45,767) ÷ 2) =
(22 × 32 × 72 × 17 × 19 × 43 × 2,551)/(709 × 3,467 × 45,767) =
62,499,999,996/112,500,000,001
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
62,499,999,996/112,500,000,001 =
62,499,999,996 ÷ 112,500,000,001 =
