2. Write the mixed repeating (recurring) decimal number as a proper fraction.
0.416666667 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 = 0.416666667
Set up the second equation.
- Number of decimal places repeating: 7
Multiply both sides of the first equation by 107 = 10,000,000
y = 0.416666667
10,000,000 × y = 10,000,000 × 0.416666667
10,000,000 × y = 4,166,666.676666667
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.
10,000,000 × y - y = 4,166,666.676666667 - 0.416666667 ⇒
(10,000,000 - 1) × y = 4,166,666.676666667 - 0.416666667 ⇒
We now have a new equation:
9,999,999 × y = 4,166,666.26
Solve for y in the new equation.
9,999,999 × y = 4,166,666.26 ⇒
y = 4,166,666.26/9,999,999
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 0.416666667
According to our calculations:
y = 4,166,666.26/9,999,999
⇒ 0.416666667 = 4,166,666.26/9,999,999
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.
0.416666667 = (4,166,666.26 × 100)/(9,999,999 × 100)
0.416666667 = 416,666,626/999,999,900
