2. Write the number as an improper fraction.
- 233.33333334 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:
233.33333334 = 233.33333334/1
Turn the top number into a whole number.
- Multiply both the top and the bottom by the same number.
- This number is: 100,000,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
233.33333334/1 =
(233.33333334 × 100,000,000)/(1 × 100,000,000) =
23,333,333,334/100,000,000
3. Reduce (simplify) the fraction above:
23,333,333,334/100,000,000
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).
23,333,333,334 = 2 × 3 × 59 × 83 × 794,137
100,000,000 = 28 × 58
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (2 × 3 × 59 × 83 × 794,137; 28 × 58) = 2
Divide both the numerator and the denominator by their GCF.
23,333,333,334/100,000,000 =
(2 × 3 × 59 × 83 × 794,137)/(28 × 58) =
((2 × 3 × 59 × 83 × 794,137) ÷ 2) / ((28 × 58) ÷ 2) =
(3 × 59 × 83 × 794,137)/(27 × 58) =
11,666,666,667/50,000,000
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.
11,666,666,667 ÷ 50,000,000 = 233, remainder = 16,666,667 ⇒
11,666,666,667 = 233 × 50,000,000 + 16,666,667 ⇒
11,666,666,667/50,000,000 =
(233 × 50,000,000 + 16,666,667) / 50,000,000 =
(233 × 50,000,000) / 50,000,000 + 16,666,667/50,000,000 =
233 + 16,666,667/50,000,000 =
233 16,666,667/50,000,000
