2. Write the mixed repeating (recurring) decimal number as a proper fraction.
0.16666669 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 = 0.16666669
Set up the second equation.
- Number of decimal places repeating: 4
Multiply both sides of the first equation by 104 = 10,000
y = 0.16666669
10,000 × y = 10,000 × 0.16666669
10,000 × y = 1,666.6669
Get the same number of decimal places as for y:
10,000 × y = 1,666.66696669
Note: 1,666.66696669 = 1,666.6669
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 = 1,666.66696669 - 0.16666669 ⇒
(10,000 - 1) × y = 1,666.66696669 - 0.16666669 ⇒
We now have a new equation:
9,999 × y = 1,666.5003
Solve for y in the new equation.
9,999 × y = 1,666.5003 ⇒
y = 1,666.5003/9,999
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 0.16666669
According to our calculations:
y = 1,666.5003/9,999
⇒ 0.16666669 = 1,666.5003/9,999
Get rid of the decimal places in the fraction above.
- Multiply the top and the bottom number by 10,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
0.16666669 = (1,666.5003 × 10,000)/(9,999 × 10,000)
0.16666669 = 16,665,003/99,990,000
3. Reduce (simplify) the fraction above:
16,665,003/99,990,000
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).
16,665,003 = 32 × 1,851,667
99,990,000 = 24 × 32 × 54 × 11 × 101
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (32 × 1,851,667; 24 × 32 × 54 × 11 × 101) = 32
Divide both the numerator and the denominator by their GCF.
16,665,003/99,990,000 =
(32 × 1,851,667)/(24 × 32 × 54 × 11 × 101) =
((32 × 1,851,667) ÷ 32) / ((24 × 32 × 54 × 11 × 101) ÷ 32) =
1,851,667/(24 × 54 × 11 × 101) =
1,851,667/11,110,000
