2. Write the pure repeating (recurring) decimal number as an improper fraction.
1.8289 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 = 1.8289
Set up the second equation.
- Number of decimal places repeating: 4
Multiply both sides of the first equation by 104 = 10,000
y = 1.8289
10,000 × y = 10,000 × 1.8289
10,000 × y = 18,289.8289
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 = 18,289.8289 - 1.8289 ⇒
(10,000 - 1) × y = 18,289.8289 - 1.8289 ⇒
We now have a new equation:
9,999 × y = 18,288
Solve for y in the new equation.
9,999 × y = 18,288 ⇒
y = 18,288/9,999
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 1.8289
According to our calculations:
y = 18,288/9,999
⇒ 1.8289 = 18,288/9,999
3. Reduce (simplify) the fraction above:
18,288/9,999
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).
18,288 = 24 × 32 × 127
9,999 = 32 × 11 × 101
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (24 × 32 × 127; 32 × 11 × 101) = 32
Divide both the numerator and the denominator by their GCF.
18,288/9,999 =
(24 × 32 × 127)/(32 × 11 × 101) =
((24 × 32 × 127) ÷ 32) / ((32 × 11 × 101) ÷ 32) =
(24 × 127)/(11 × 101) =
2,032/1,111
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.
2,032 ÷ 1,111 = 1, remainder = 921 ⇒
2,032 = 1 × 1,111 + 921 ⇒
2,032/1,111 =
(1 × 1,111 + 921) / 1,111 =
(1 × 1,111) / 1,111 + 921/1,111 =
1 + 921/1,111 =
1 921/1,111
2,032/1,111 ~ Equivalent fractions.
