2. Write the number as an improper fraction.
- 2.36368 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:
2.36368 = 2.36368/1
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.
2.36368/1 =
(2.36368 × 100,000)/(1 × 100,000) =
236,368/100,000
3. Reduce (simplify) the fraction above:
236,368/100,000
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).
236,368 = 24 × 11 × 17 × 79
100,000 = 25 × 55
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (24 × 11 × 17 × 79; 25 × 55) = 24
Divide both the numerator and the denominator by their GCF.
236,368/100,000 =
(24 × 11 × 17 × 79)/(25 × 55) =
((24 × 11 × 17 × 79) ÷ 24) / ((25 × 55) ÷ 24) =
(11 × 17 × 79)/(2 × 55) =
14,773/6,250
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.
14,773 ÷ 6,250 = 2, remainder = 2,273 ⇒
14,773 = 2 × 6,250 + 2,273 ⇒
14,773/6,250 =
(2 × 6,250 + 2,273) / 6,250 =
(2 × 6,250) / 6,250 + 2,273/6,250 =
2 + 2,273/6,250 =
2 2,273/6,250
