2. Write the mixed repeating (recurring) decimal number as a proper fraction.
0.41666667 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 = 0.41666667
Set up the second equation.
- Number of decimal places repeating: 5
Multiply both sides of the first equation by 105 = 100,000
y = 0.41666667
100,000 × y = 100,000 × 0.41666667
100,000 × y = 41,666.66766667
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 × y - y = 41,666.66766667 - 0.41666667 ⇒
(100,000 - 1) × y = 41,666.66766667 - 0.41666667 ⇒
We now have a new equation:
99,999 × y = 41,666.251
Solve for y in the new equation.
99,999 × y = 41,666.251 ⇒
y = 41,666.251/99,999
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 0.41666667
According to our calculations:
y = 41,666.251/99,999
⇒ 0.41666667 = 41,666.251/99,999
Get rid of the decimal places in the fraction above.
- Multiply the top and the bottom number by 1,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
0.41666667 = (41,666.251 × 1,000)/(99,999 × 1,000)
0.41666667 = 41,666,251/99,999,000
3. Reduce (simplify) the fraction above:
41,666,251/99,999,000
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).
41,666,251 = 11 × 251 × 15,091
99,999,000 = 23 × 32 × 53 × 41 × 271
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 (11 × 251 × 15,091; 23 × 32 × 53 × 41 × 271) = 1
The numerator and the denominator are coprime numbers (no common prime factors, GCF = 1). So, the fraction cannot be reduced (simplified): irreducible fraction.
41,666,251/99,999,000 ~ Equivalent fractions.
- The above fraction cannot be reduced.
- That is, it has the smallest possible numerator and denominator.
