2. Write the pure repeating (recurring) decimal number as an improper fraction.
17.8333336 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 = 17.8333336
Set up the second equation.
- Number of decimal places repeating: 7
Multiply both sides of the first equation by 107 = 10,000,000
y = 17.8333336
10,000,000 × y = 10,000,000 × 17.8333336
10,000,000 × y = 178,333,336.8333336
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.
10,000,000 × y - y = 178,333,336.8333336 - 17.8333336 ⇒
(10,000,000 - 1) × y = 178,333,336.8333336 - 17.8333336 ⇒
We now have a new equation:
9,999,999 × y = 178,333,319
Solve for y in the new equation.
9,999,999 × y = 178,333,319 ⇒
y = 178,333,319/9,999,999
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 17.8333336
According to our calculations:
y = 178,333,319/9,999,999
⇒ 17.8333336 = 178,333,319/9,999,999
3. Reduce (simplify) the fraction above:
178,333,319/9,999,999

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).
178,333,319 is a prime number, it cannot be factored into other prime factors
9,999,999 = 32 × 239 × 4,649
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
But, the numerator and the denominator have no common factors.
GCF (178,333,319; 32 × 239 × 4,649) = 1
The numerator and the denominator are coprime numbers (no common prime factors, GCF = 1). So, the fraction cannot be reduced (simplified): irreducible fraction.
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.
178,333,319 ÷ 9,999,999 = 17, remainder = 8,333,336 ⇒
178,333,319 = 17 × 9,999,999 + 8,333,336 ⇒
178,333,319/9,999,999 =
(17 × 9,999,999 + 8,333,336) / 9,999,999 =
(17 × 9,999,999) / 9,999,999 + 8,333,336/9,999,999 =
17 + 8,333,336/9,999,999 =
17 8,333,336/9,999,999
