2. Write the number as an improper fraction.
- 5.808 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:
5.808 = 5.808/1
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.
5.808/1 =
(5.808 × 1,000)/(1 × 1,000) =
5,808/1,000
3. Reduce (simplify) the fraction above:
5,808/1,000
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).
5,808 = 24 × 3 × 112
1,000 = 23 × 53
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (24 × 3 × 112; 23 × 53) = 23
Divide both the numerator and the denominator by their GCF.
5,808/1,000 =
(24 × 3 × 112)/(23 × 53) =
((24 × 3 × 112) ÷ 23) / ((23 × 53) ÷ 23) =
(2 × 3 × 112)/53 =
726/125
