2. Write the number as an improper fraction.
- 1.335 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:
1.335 = 1.335/1
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.
1.335/1 =
(1.335 × 1,000)/(1 × 1,000) =
1,335/1,000
3. Reduce (simplify) the fraction above:
1,335/1,000
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).
1,335 = 3 × 5 × 89
1,000 = 23 × 53
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (3 × 5 × 89; 23 × 53) = 5
Divide both the numerator and the denominator by their GCF.
1,335/1,000 =
(3 × 5 × 89)/(23 × 53) =
((3 × 5 × 89) ÷ 5) / ((23 × 53) ÷ 5) =
(3 × 89)/(23 × 52) =
267/200
