12.0740748/1 =
(12.0740748 × 10,000,000)/(1 × 10,000,000) =
120,740,748/10,000,000
3. Reduce (simplify) the fraction above:
120,740,748/10,000,000
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).
120,740,748 = 22 × 3 × 10,061,729
10,000,000 = 27 × 57
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (22 × 3 × 10,061,729; 27 × 57) = 22
Divide both the numerator and the denominator by their GCF.
120,740,748/10,000,000 =
(22 × 3 × 10,061,729)/(27 × 57) =
((22 × 3 × 10,061,729) ÷ 22) / ((27 × 57) ÷ 22) =
(3 × 10,061,729)/(25 × 57) =
30,185,187/2,500,000
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.
30,185,187 ÷ 2,500,000 = 12, remainder = 185,187 ⇒
30,185,187 = 12 × 2,500,000 + 185,187 ⇒
30,185,187/2,500,000 =
(12 × 2,500,000 + 185,187) / 2,500,000 =
(12 × 2,500,000) / 2,500,000 + 185,187/2,500,000 =
12 + 185,187/2,500,000 =
12 185,187/2,500,000
