2. Write the pure repeating (recurring) decimal number as an improper fraction.
10.67 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 = 10.67
Set up the second equation.
- Number of decimal places repeating: 2
Multiply both sides of the first equation by 102 = 100
y = 10.67
100 × y = 100 × 10.67
100 × y = 1,067.67
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 = 1,067.67 - 10.67 ⇒
(100 - 1) × y = 1,067.67 - 10.67 ⇒
We now have a new equation:
99 × y = 1,057
Solve for y in the new equation.
99 × y = 1,057 ⇒
y = 1,057/99
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 10.67
According to our calculations:
y = 1,057/99
⇒ 10.67 = 1,057/99
3. Reduce (simplify) the fraction above:
1,057/99
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).
1,057 = 7 × 151
99 = 32 × 11
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 (7 × 151; 32 × 11) = 1
The numerator and the denominator are coprime numbers (no common prime factors, GCF = 1). So, the fraction cannot be reduced (simplified): irreducible fraction.
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.
1,057 ÷ 99 = 10, remainder = 67 ⇒
1,057 = 10 × 99 + 67 ⇒
1,057/99 =
(10 × 99 + 67) / 99 =
(10 × 99) / 99 + 67/99 =
10 + 67/99 =
10 67/99
1,057/99 ~ 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.
1,057/99 = (1,057 × 5)/(99 × 5) = 5,285/495
Example 2. By expanding the fraction by 9.
1,057/99 = (1,057 × 9)/(99 × 9) = 9,513/891
- Of course, the above fractions are reducing...
- ... to the initial fraction: 1,057/99
:: Final answer ::
Written in 4 different ways
