2. Write the mixed repeating (recurring) decimal number as a proper fraction.
0.57143 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 = 0.57143
Set up the second equation.
- Number of decimal places repeating: 3
Multiply both sides of the first equation by 103 = 1,000
y = 0.57143
1,000 × y = 1,000 × 0.57143
1,000 × y = 571.43143
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.
1,000 × y - y = 571.43143 - 0.57143 ⇒
(1,000 - 1) × y = 571.43143 - 0.57143 ⇒
We now have a new equation:
999 × y = 570.86
Solve for y in the new equation.
999 × y = 570.86 ⇒
y = 570.86/999
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 0.57143
According to our calculations:
y = 570.86/999
⇒ 0.57143 = 570.86/999
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.
0.57143 = (570.86 × 100)/(999 × 100)
0.57143 = 57,086/99,900
3. Reduce (simplify) the fraction above:
57,086/99,900
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).
57,086 = 2 × 17 × 23 × 73
99,900 = 22 × 33 × 52 × 37
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (2 × 17 × 23 × 73; 22 × 33 × 52 × 37) = 2
Divide both the numerator and the denominator by their GCF.
57,086/99,900 =
(2 × 17 × 23 × 73)/(22 × 33 × 52 × 37) =
((2 × 17 × 23 × 73) ÷ 2) / ((22 × 33 × 52 × 37) ÷ 2) =
(17 × 23 × 73)/(2 × 33 × 52 × 37) =
28,543/49,950
