2. Write the number as an improper fraction.
- 17.335 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:
17.335 = 17.335/1
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.
17.335/1 =
(17.335 × 1,000)/(1 × 1,000) =
17,335/1,000
3. Reduce (simplify) the fraction above:
17,335/1,000
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).
17,335 = 5 × 3,467
1,000 = 23 × 53
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (5 × 3,467; 23 × 53) = 5
Divide both the numerator and the denominator by their GCF.
17,335/1,000 =
(5 × 3,467)/(23 × 53) =
((5 × 3,467) ÷ 5) / ((23 × 53) ÷ 5) =
3,467/(23 × 52) =
3,467/200
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.
3,467 ÷ 200 = 17, remainder = 67 ⇒
3,467 = 17 × 200 + 67 ⇒
3,467/200 =
(17 × 200 + 67) / 200 =
(17 × 200) / 200 + 67/200 =
17 + 67/200 =
17 67/200
