2. Write the number as an improper fraction.
- 9.33333333336 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:
9.33333333336 = 9.33333333336/1
Turn the top number into a whole number.
- Multiply both the top and the bottom by the same number.
- This number is: 100,000,000,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
9.33333333336/1 =
(9.33333333336 × 100,000,000,000)/(1 × 100,000,000,000) =
933,333,333,336/100,000,000,000
3. Reduce (simplify) the fraction above:
933,333,333,336/100,000,000,000
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).
933,333,333,336 = 23 × 32 × 563 × 659 × 34,939
100,000,000,000 = 211 × 511
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (23 × 32 × 563 × 659 × 34,939; 211 × 511) = 23
Divide both the numerator and the denominator by their GCF.
933,333,333,336/100,000,000,000 =
(23 × 32 × 563 × 659 × 34,939)/(211 × 511) =
((23 × 32 × 563 × 659 × 34,939) ÷ 23) / ((211 × 511) ÷ 23) =
(32 × 563 × 659 × 34,939)/(28 × 511) =
116,666,666,667/12,500,000,000
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.
116,666,666,667 ÷ 12,500,000,000 = 9, remainder = 4,166,666,667 ⇒
116,666,666,667 = 9 × 12,500,000,000 + 4,166,666,667 ⇒
116,666,666,667/12,500,000,000 =
(9 × 12,500,000,000 + 4,166,666,667) / 12,500,000,000 =
(9 × 12,500,000,000) / 12,500,000,000 + 4,166,666,667/12,500,000,000 =
9 + 4,166,666,667/12,500,000,000 =
9 4,166,666,667/12,500,000,000
