2. Write the number as an improper fraction.
- 14.836 can be written as an improper fraction.
- An improper fraction = the numerator is larger than or equal to the denominator..
Write down the number divided by 1, as a fraction:
14.836 = 14.836/1
Turn the top number into a whole number.
- Multiply both the top and the bottom by the same number.
- This number is: 1,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
14.836/1 =
(14.836 × 1,000)/(1 × 1,000) =
14,836/1,000
3. Reduce (simplify) the fraction above:
14,836/1,000
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).
14,836 = 22 × 3,709
1,000 = 23 × 53
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (22 × 3,709; 23 × 53) = 22
Divide both the numerator and the denominator by their GCF.
14,836/1,000 =
(22 × 3,709)/(23 × 53) =
((22 × 3,709) ÷ 22) / ((23 × 53) ÷ 22) =
3,709/(2 × 53) =
3,709/250
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.
3,709 ÷ 250 = 14, remainder = 209 ⇒
3,709 = 14 × 250 + 209 ⇒
3,709/250 =
(14 × 250 + 209) / 250 =
(14 × 250) / 250 + 209/250 =
14 + 209/250 =
14 209/250
