2. Write the number as an improper fraction.
- 1.006 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:
1.006 = 1.006/1
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.
1.006/1 =
(1.006 × 1,000)/(1 × 1,000) =
1,006/1,000
3. Reduce (simplify) the fraction above:
1,006/1,000
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).
1,006 = 2 × 503
1,000 = 23 × 53
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (2 × 503; 23 × 53) = 2
Divide both the numerator and the denominator by their GCF.
1,006/1,000 =
(2 × 503)/(23 × 53) =
((2 × 503) ÷ 2) / ((23 × 53) ÷ 2) =
503/(22 × 53) =
503/500
