12.0740745 = 12.0740745/1
Turn the top number into a whole number.
- Multiply both the top and the bottom by the same number.
- This number is: 10,000,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
12.0740745/1 =
(12.0740745 × 10,000,000)/(1 × 10,000,000) =
120,740,745/10,000,000
3. Reduce (simplify) the fraction above:
120,740,745/10,000,000
to the lowest terms, to its simplest equivalent form, irreducible.
To reduce a fraction to the lowest terms divide the numerator and denominator by their greatest (highest) common factor (divisor), GCF.
Factor the numerator and denominator (prime factorization).
120,740,745 = 3 × 5 × 8,049,383
10,000,000 = 27 × 57
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (3 × 5 × 8,049,383; 27 × 57) = 5
Divide both the numerator and the denominator by their GCF.
120,740,745/10,000,000 =
(3 × 5 × 8,049,383)/(27 × 57) =
((3 × 5 × 8,049,383) ÷ 5) / ((27 × 57) ÷ 5) =
(3 × 8,049,383)/(27 × 56) =
24,148,149/2,000,000
4. The fraction is an improper one, rewrite it as a mixed number (mixed fraction):
- A mixed number = an integer number and a proper fraction, of the same sign.
- Example 1: 2 1/5; Example 2: - 1 3/7.
- A proper fraction = the numerator is smaller than the denominator.
24,148,149 ÷ 2,000,000 = 12, remainder = 148,149 ⇒
24,148,149 = 12 × 2,000,000 + 148,149 ⇒
24,148,149/2,000,000 =
(12 × 2,000,000 + 148,149) / 2,000,000 =
(12 × 2,000,000) / 2,000,000 + 148,149/2,000,000 =
12 + 148,149/2,000,000 =
12 148,149/2,000,000
