2. Write the number as an improper fraction.
- 1.5334 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:
1.5334 = 1.5334/1
Turn the top number into a whole number.
- Multiply both the top and the bottom by the same number.
- This number is: 10,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
1.5334/1 =
(1.5334 × 10,000)/(1 × 10,000) =
15,334/10,000
3. Reduce (simplify) the fraction above:
15,334/10,000
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).
15,334 = 2 × 11 × 17 × 41
10,000 = 24 × 54
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (2 × 11 × 17 × 41; 24 × 54) = 2
Divide both the numerator and the denominator by their GCF.
15,334/10,000 =
(2 × 11 × 17 × 41)/(24 × 54) =
((2 × 11 × 17 × 41) ÷ 2) / ((24 × 54) ÷ 2) =
(11 × 17 × 41)/(23 × 54) =
7,667/5,000
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.
7,667 ÷ 5,000 = 1, remainder = 2,667 ⇒
7,667 = 1 × 5,000 + 2,667 ⇒
7,667/5,000 =
(1 × 5,000 + 2,667) / 5,000 =
(1 × 5,000) / 5,000 + 2,667/5,000 =
1 + 2,667/5,000 =
1 2,667/5,000
