2. Write the mixed repeating (recurring) decimal number as an improper fraction.
111.681 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 = 111.681
Set up the second equation.
- Number of decimal places repeating: 2
Multiply both sides of the first equation by 102 = 100
y = 111.681
100 × y = 100 × 111.681
100 × y = 11,168.181
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 × y - y = 11,168.181 - 111.681 ⇒
(100 - 1) × y = 11,168.181 - 111.681 ⇒
We now have a new equation:
99 × y = 11,056.5
Solve for y in the new equation.
99 × y = 11,056.5 ⇒
y = 11,056.5/99
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 111.681
According to our calculations:
y = 11,056.5/99
⇒ 111.681 = 11,056.5/99
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.
111.681 = (11,056.5 × 10)/(99 × 10)
111.681 = 110,565/990
3. Reduce (simplify) the fraction above:
110,565/990
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).
110,565 = 35 × 5 × 7 × 13
990 = 2 × 32 × 5 × 11
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (35 × 5 × 7 × 13; 2 × 32 × 5 × 11) = 32 × 5
Divide both the numerator and the denominator by their GCF.
110,565/990 =
(35 × 5 × 7 × 13)/(2 × 32 × 5 × 11) =
((35 × 5 × 7 × 13) ÷ (32 × 5)) / ((2 × 32 × 5 × 11) ÷ (32 × 5)) =
(33 × 7 × 13)/(2 × 11) =
2,457/22
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.
2,457 ÷ 22 = 111, remainder = 15 ⇒
2,457 = 111 × 22 + 15 ⇒
2,457/22 =
(111 × 22 + 15) / 22 =
(111 × 22) / 22 + 15/22 =
111 + 15/22 =
111 15/22
2,457/22 ~ Equivalent fractions.
- The above fraction cannot be reduced.
- That is, it has the smallest possible numerator and denominator.
By expanding it we can build up equivalent fractions.
Multiply the numerator & the denominator by the same number.
Example 1. By expanding the fraction by 5.
2,457/22 = (2,457 × 5)/(22 × 5) = 12,285/110
Example 2. By expanding the fraction by 8.
2,457/22 = (2,457 × 8)/(22 × 8) = 19,656/176
- Of course, the above fractions are reducing...
- ... to the initial fraction: 2,457/22
