2. Write the number as an improper fraction.
- 35.002 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:
35.002 = 35.002/1
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.
35.002/1 =
(35.002 × 1,000)/(1 × 1,000) =
35,002/1,000
3. Reduce (simplify) the fraction above:
35,002/1,000
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).
35,002 = 2 × 11 × 37 × 43
1,000 = 23 × 53
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (2 × 11 × 37 × 43; 23 × 53) = 2
Divide both the numerator and the denominator by their GCF.
35,002/1,000 =
(2 × 11 × 37 × 43)/(23 × 53) =
((2 × 11 × 37 × 43) ÷ 2) / ((23 × 53) ÷ 2) =
(11 × 37 × 43)/(22 × 53) =
17,501/500
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.
17,501 ÷ 500 = 35, remainder = 1 ⇒
17,501 = 35 × 500 + 1 ⇒
17,501/500 =
(35 × 500 + 1) / 500 =
(35 × 500) / 500 + 1/500 =
35 + 1/500 =
35 1/500
