2. Write the pure repeating (recurring) decimal number as an improper fraction.
50.18 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 = 50.18
Set up the second equation.
- Number of decimal places repeating: 2
Multiply both sides of the first equation by 102 = 100
y = 50.18
100 × y = 100 × 50.18
100 × y = 5,018.18
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 = 5,018.18 - 50.18 ⇒
(100 - 1) × y = 5,018.18 - 50.18 ⇒
We now have a new equation:
99 × y = 4,968
Solve for y in the new equation.
99 × y = 4,968 ⇒
y = 4,968/99
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 50.18
According to our calculations:
y = 4,968/99
⇒ 50.18 = 4,968/99
3. Reduce (simplify) the fraction above:
4,968/99
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).
4,968 = 23 × 33 × 23
99 = 32 × 11
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (23 × 33 × 23; 32 × 11) = 32
Divide both the numerator and the denominator by their GCF.
4,968/99 =
(23 × 33 × 23)/(32 × 11) =
((23 × 33 × 23) ÷ 32) / ((32 × 11) ÷ 32) =
(23 × 3 × 23)/11 =
552/11
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.
552 ÷ 11 = 50, remainder = 2 ⇒
552 = 50 × 11 + 2 ⇒
552/11 =
(50 × 11 + 2) / 11 =
(50 × 11) / 11 + 2/11 =
50 + 2/11 =
50 2/11
552/11 ~ 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.
552/11 = (552 × 5)/(11 × 5) = 2,760/55
Example 2. By expanding the fraction by 6.
552/11 = (552 × 6)/(11 × 6) = 3,312/66
- Of course, the above fractions are reducing...
- ... to the initial fraction: 552/11
:: Final answer ::
