2. Write the pure repeating (recurring) decimal number as a proper fraction.
0.53333334 can be written as a proper fraction.
- The numerator is smaller than the denominator.
Set up the first equation.
- Let y equal the decimal number:
y = 0.53333334
Set up the second equation.
- Number of decimal places repeating: 8
Multiply both sides of the first equation by 108 = 100,000,000
y = 0.53333334
100,000,000 × y = 100,000,000 × 0.53333334
100,000,000 × y = 53,333,334.53333334
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.
100,000,000 × y - y = 53,333,334.53333334 - 0.53333334 ⇒
(100,000,000 - 1) × y = 53,333,334.53333334 - 0.53333334 ⇒
We now have a new equation:
99,999,999 × y = 53,333,334
Solve for y in the new equation.
99,999,999 × y = 53,333,334 ⇒
y = 53,333,334/99,999,999
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 0.53333334
According to our calculations:
y = 53,333,334/99,999,999
⇒ 0.53333334 = 53,333,334/99,999,999
3. Reduce (simplify) the fraction above:
53,333,334/99,999,999
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).
53,333,334 = 2 × 32 × 2,962,963
99,999,999 = 32 × 11 × 73 × 101 × 137
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (2 × 32 × 2,962,963; 32 × 11 × 73 × 101 × 137) = 32
Divide both the numerator and the denominator by their GCF.
53,333,334/99,999,999 =
(2 × 32 × 2,962,963)/(32 × 11 × 73 × 101 × 137) =
((2 × 32 × 2,962,963) ÷ 32) / ((32 × 11 × 73 × 101 × 137) ÷ 32) =
(2 × 2,962,963)/(11 × 73 × 101 × 137) =
5,925,926/11,111,111
