Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
145,833,333,342/499,999,999,989
- The integer number above the bar is called numerator: 145,833,333,342
- The integer number below the bar is called denominator: 499,999,999,989
- 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 = 145,833,333,342 ÷ 499,999,999,989
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:
145,833,333,342 = 2 × 3 × 24,305,555,557
145,833,333,342 is a composite number.
499,999,999,989 = 3 × 7 × 59 × 67 × 6,023,153
499,999,999,989 is a composite number.
145,833,333,342/499,999,999,989 =
(145,833,333,342 ÷ 3) / (499,999,999,989 ÷ 3) =
48,611,111,114/166,666,666,663
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.
145,833,333,342/499,999,999,989 =
(2 × 3 × 24,305,555,557)/(3 × 7 × 59 × 67 × 6,023,153) =
((2 × 3 × 24,305,555,557) ÷ 3) / ((3 × 7 × 59 × 67 × 6,023,153) ÷ 3) =
(2 × 24,305,555,557)/(7 × 59 × 67 × 6,023,153) =
48,611,111,114/166,666,666,663
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
48,611,111,114/166,666,666,663 =
48,611,111,114 ÷ 166,666,666,663 =
0.29166666669 ≈
