Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
41,666,666,638/74,999,999,948
- The integer number above the bar is called numerator: 41,666,666,638
- The integer number below the bar is called denominator: 74,999,999,948
- 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 = 41,666,666,638 ÷ 74,999,999,948
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:
41,666,666,638 = 2 × 20,833,333,319
41,666,666,638 is a composite number.
Written with exponents:
74,999,999,948 = 2 × 2 × 193 × 97,150,259 = 22 × 193 × 97,150,259
74,999,999,948 is a composite number.
41,666,666,638/74,999,999,948 =
(41,666,666,638 ÷ 2) / (74,999,999,948 ÷ 2) =
20,833,333,319/37,499,999,974
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.
41,666,666,638/74,999,999,948 =
(2 × 20,833,333,319)/(22 × 193 × 97,150,259) =
((2 × 20,833,333,319) ÷ 2) / ((22 × 193 × 97,150,259) ÷ 2) =
20,833,333,319/(2 × 193 × 97,150,259) =
20,833,333,319/37,499,999,974
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
20,833,333,319/37,499,999,974 =
20,833,333,319 ÷ 37,499,999,974 =
