2. Write the mixed repeating (recurring) decimal number as an improper fraction.
22.28576 can be written as an improper fraction.
- The numerator is larger than or equal to the denominator.
Set up the first equation.
- Let y equal the decimal number:
y = 22.28576
Set up the second equation.
- Number of decimal places repeating: 4
Multiply both sides of the first equation by 104 = 10,000
y = 22.28576
10,000 × y = 10,000 × 22.28576
10,000 × y = 222,857.68576
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 = 222,857.68576 - 22.28576 ⇒
(10,000 - 1) × y = 222,857.68576 - 22.28576 ⇒
We now have a new equation:
9,999 × y = 222,835.4
Solve for y in the new equation.
9,999 × y = 222,835.4 ⇒
y = 222,835.4/9,999
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 22.28576
According to our calculations:
y = 222,835.4/9,999
⇒ 22.28576 = 222,835.4/9,999
Get rid of the decimal places in the fraction above.
- Multiply the top and the bottom number by 10.
- 1 followed by as many 0-s as the number of digits after the decimal point.
22.28576 = (222,835.4 × 10)/(9,999 × 10)
22.28576 = 2,228,354/99,990
3. Reduce (simplify) the fraction above:
2,228,354/99,990
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).
2,228,354 = 2 × 563 × 1,979
99,990 = 2 × 32 × 5 × 11 × 101
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (2 × 563 × 1,979; 2 × 32 × 5 × 11 × 101) = 2
Divide both the numerator and the denominator by their GCF.
2,228,354/99,990 =
(2 × 563 × 1,979)/(2 × 32 × 5 × 11 × 101) =
((2 × 563 × 1,979) ÷ 2) / ((2 × 32 × 5 × 11 × 101) ÷ 2) =
(563 × 1,979)/(32 × 5 × 11 × 101) =
1,114,177/49,995
4. The fraction is an improper one, rewrite it as a mixed number (mixed fraction):
- A mixed number = an integer number and a proper fraction, of the same sign.
- Example 1: 2 1/5; Example 2: - 1 3/7.
- A proper fraction = the numerator is smaller than the denominator.
1,114,177 ÷ 49,995 = 22, remainder = 14,287 ⇒
1,114,177 = 22 × 49,995 + 14,287 ⇒
1,114,177/49,995 =
(22 × 49,995 + 14,287) / 49,995 =
(22 × 49,995) / 49,995 + 14,287/49,995 =
22 + 14,287/49,995 =
22 14,287/49,995
