2. Write the mixed repeating (recurring) decimal number as an improper fraction.
4.017345 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 = 4.017345
Set up the second equation.
- Number of decimal places repeating: 1
Multiply both sides of the first equation by 101 = 10
y = 4.017345
10 × y = 10 × 4.017345
10 × y = 40.17345
Get the same number of decimal places as for y:
10 × y = 40.173455
Note: 40.173455 = 40.17345
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 × y - y = 40.173455 - 4.017345 ⇒
(10 - 1) × y = 40.173455 - 4.017345 ⇒
We now have a new equation:
9 × y = 36.15611
Solve for y in the new equation.
9 × y = 36.15611 ⇒
y = 36.15611/9
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 4.017345
According to our calculations:
y = 36.15611/9
⇒ 4.017345 = 36.15611/9
Get rid of the decimal places in the fraction above.
- Multiply the top and the bottom number by 100,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
4.017345 = (36.15611 × 100,000)/(9 × 100,000)
4.017345 = 3,615,611/900,000
3. Reduce (simplify) the fraction above:
3,615,611/900,000
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).
3,615,611 = 17 × 212,683
900,000 = 25 × 32 × 55
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 (17 × 212,683; 25 × 32 × 55) = 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.
3,615,611 ÷ 900,000 = 4, remainder = 15,611 ⇒
3,615,611 = 4 × 900,000 + 15,611 ⇒
3,615,611/900,000 =
(4 × 900,000 + 15,611) / 900,000 =
(4 × 900,000) / 900,000 + 15,611/900,000 =
4 + 15,611/900,000 =
4 15,611/900,000
