2. Write the mixed repeating (recurring) decimal number as an improper fraction.
115.1564 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 = 115.1564
Set up the second equation.
- Number of decimal places repeating: 2
Multiply both sides of the first equation by 102 = 100
y = 115.1564
100 × y = 100 × 115.1564
100 × y = 11,515.64
Get the same number of decimal places as for y:
100 × y = 11,515.6464
Note: 11,515.6464 = 11,515.64
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 = 11,515.6464 - 115.1564 ⇒
(100 - 1) × y = 11,515.6464 - 115.1564 ⇒
We now have a new equation:
99 × y = 11,400.49
Solve for y in the new equation.
99 × y = 11,400.49 ⇒
y = 11,400.49/99
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 115.1564
According to our calculations:
y = 11,400.49/99
⇒ 115.1564 = 11,400.49/99
Get rid of the decimal places in the fraction above.
- Multiply the top and the bottom number by 100.
- 1 followed by as many 0-s as the number of digits after the decimal point.
115.1564 = (11,400.49 × 100)/(99 × 100)
115.1564 = 1,140,049/9,900
3. Reduce (simplify) the fraction above:
1,140,049/9,900
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).
1,140,049 = 79 × 14,431
9,900 = 22 × 32 × 52 × 11
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 (79 × 14,431; 22 × 32 × 52 × 11) = 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.
1,140,049 ÷ 9,900 = 115, remainder = 1,549 ⇒
1,140,049 = 115 × 9,900 + 1,549 ⇒
1,140,049/9,900 =
(115 × 9,900 + 1,549) / 9,900 =
(115 × 9,900) / 9,900 + 1,549/9,900 =
115 + 1,549/9,900 =
115 1,549/9,900
1,140,049/9,900 ~ Equivalent fractions.
- The above fraction cannot be reduced.
- That is, it has the smallest possible numerator and denominator.
