2. Write the pure repeating (recurring) decimal number as an improper fraction.
7.397 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 = 7.397
Set up the second equation.
- Number of decimal places repeating: 3
Multiply both sides of the first equation by 103 = 1,000
y = 7.397
1,000 × y = 1,000 × 7.397
1,000 × y = 7,397.397
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.
1,000 × y - y = 7,397.397 - 7.397 ⇒
(1,000 - 1) × y = 7,397.397 - 7.397 ⇒
We now have a new equation:
999 × y = 7,390
Solve for y in the new equation.
999 × y = 7,390 ⇒
y = 7,390/999
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 7.397
According to our calculations:
y = 7,390/999
⇒ 7.397 = 7,390/999
3. Reduce (simplify) the fraction above:
7,390/999
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).
7,390 = 2 × 5 × 739
999 = 33 × 37
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 (2 × 5 × 739; 33 × 37) = 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.
7,390 ÷ 999 = 7, remainder = 397 ⇒
7,390 = 7 × 999 + 397 ⇒
7,390/999 =
(7 × 999 + 397) / 999 =
(7 × 999) / 999 + 397/999 =
7 + 397/999 =
7 397/999
7,390/999 ~ 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 4.
7,390/999 = (7,390 × 4)/(999 × 4) = 29,560/3,996
Example 2. By expanding the fraction by 8.
7,390/999 = (7,390 × 8)/(999 × 8) = 59,120/7,992
- Of course, the above fractions are reducing...
- ... to the initial fraction: 7,390/999
