2. Write the mixed repeating (recurring) decimal number as an improper fraction.
10.6666668 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 = 10.6666668
Set up the second equation.
- Number of decimal places repeating: 2
Multiply both sides of the first equation by 102 = 100
y = 10.6666668
100 × y = 100 × 10.6666668
100 × y = 1,066.66668
Get the same number of decimal places as for y:
100 × y = 1,066.6666868
Note: 1,066.6666868 = 1,066.66668
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.
100 × y - y = 1,066.6666868 - 10.6666668 ⇒
(100 - 1) × y = 1,066.6666868 - 10.6666668 ⇒
We now have a new equation:
99 × y = 1,056.00002
Solve for y in the new equation.
99 × y = 1,056.00002 ⇒
y = 1,056.00002/99
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 10.6666668
According to our calculations:
y = 1,056.00002/99
⇒ 10.6666668 = 1,056.00002/99
Get rid of the decimal places in the fraction above.
- Multiply the top and the bottom number by 100,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
10.6666668 = (1,056.00002 × 100,000)/(99 × 100,000)
10.6666668 = 105,600,002/9,900,000
3. Reduce (simplify) the fraction above:
105,600,002/9,900,000
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).
105,600,002 = 2 × 43 × 691 × 1,777
9,900,000 = 25 × 32 × 55 × 11
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (2 × 43 × 691 × 1,777; 25 × 32 × 55 × 11) = 2
Divide both the numerator and the denominator by their GCF.
105,600,002/9,900,000 =
(2 × 43 × 691 × 1,777)/(25 × 32 × 55 × 11) =
((2 × 43 × 691 × 1,777) ÷ 2) / ((25 × 32 × 55 × 11) ÷ 2) =
(43 × 691 × 1,777)/(24 × 32 × 55 × 11) =
52,800,001/4,950,000
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.
52,800,001 ÷ 4,950,000 = 10, remainder = 3,300,001 ⇒
52,800,001 = 10 × 4,950,000 + 3,300,001 ⇒
52,800,001/4,950,000 =
(10 × 4,950,000 + 3,300,001) / 4,950,000 =
(10 × 4,950,000) / 4,950,000 + 3,300,001/4,950,000 =
10 + 3,300,001/4,950,000 =
10 3,300,001/4,950,000
