2. Write the number as an improper fraction.
- 3.34536 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:
3.34536 = 3.34536/1
Turn the top number into a whole number.
- Multiply both the top and the bottom by the same number.
- This number is: 100,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
3.34536/1 =
(3.34536 × 100,000)/(1 × 100,000) =
334,536/100,000
3. Reduce (simplify) the fraction above:
334,536/100,000
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).
334,536 = 23 × 3 × 53 × 263
100,000 = 25 × 55
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (23 × 3 × 53 × 263; 25 × 55) = 23
Divide both the numerator and the denominator by their GCF.
334,536/100,000 =
(23 × 3 × 53 × 263)/(25 × 55) =
((23 × 3 × 53 × 263) ÷ 23) / ((25 × 55) ÷ 23) =
(3 × 53 × 263)/(22 × 55) =
41,817/12,500
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.
41,817 ÷ 12,500 = 3, remainder = 4,317 ⇒
41,817 = 3 × 12,500 + 4,317 ⇒
41,817/12,500 =
(3 × 12,500 + 4,317) / 12,500 =
(3 × 12,500) / 12,500 + 4,317/12,500 =
3 + 4,317/12,500 =
3 4,317/12,500
