2. Write the pure repeating (recurring) decimal number as an improper fraction.
5.7698 can be written as an improper fraction.
- The numerator is larger than or equal to the denominator.
Set up the first equation.
- Let y equal the decimal number:
y = 5.7698
Set up the second equation.
- Number of decimal places repeating: 4
Multiply both sides of the first equation by 104 = 10,000
y = 5.7698
10,000 × y = 10,000 × 5.7698
10,000 × y = 57,698.7698
Subtract the first equation from the second one.
- Having the same number of decimal places ...
- The repeating pattern drops off by subtracting the two equations.
10,000 × y - y = 57,698.7698 - 5.7698 ⇒
(10,000 - 1) × y = 57,698.7698 - 5.7698 ⇒
We now have a new equation:
9,999 × y = 57,693
Solve for y in the new equation.
9,999 × y = 57,693 ⇒
y = 57,693/9,999
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 5.7698
According to our calculations:
y = 57,693/9,999
⇒ 5.7698 = 57,693/9,999
3. Reduce (simplify) the fraction above:
57,693/9,999
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).
57,693 = 3 × 19,231
9,999 = 32 × 11 × 101
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (3 × 19,231; 32 × 11 × 101) = 3
Divide both the numerator and the denominator by their GCF.
57,693/9,999 =
(3 × 19,231)/(32 × 11 × 101) =
((3 × 19,231) ÷ 3) / ((32 × 11 × 101) ÷ 3) =
19,231/(3 × 11 × 101) =
19,231/3,333
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.
19,231 ÷ 3,333 = 5, remainder = 2,566 ⇒
19,231 = 5 × 3,333 + 2,566 ⇒
19,231/3,333 =
(5 × 3,333 + 2,566) / 3,333 =
(5 × 3,333) / 3,333 + 2,566/3,333 =
5 + 2,566/3,333 =
5 2,566/3,333
