2. Write the mixed repeating (recurring) decimal number as an improper fraction.
4.31046 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 = 4.31046
Set up the second equation.
- Number of decimal places repeating: 4
Multiply both sides of the first equation by 104 = 10,000
y = 4.31046
10,000 × y = 10,000 × 4.31046
10,000 × y = 43,104.61046
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.
10,000 × y - y = 43,104.61046 - 4.31046 ⇒
(10,000 - 1) × y = 43,104.61046 - 4.31046 ⇒
We now have a new equation:
9,999 × y = 43,100.3
Solve for y in the new equation.
9,999 × y = 43,100.3 ⇒
y = 43,100.3/9,999
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 4.31046
According to our calculations:
y = 43,100.3/9,999
⇒ 4.31046 = 43,100.3/9,999
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.
4.31046 = (43,100.3 × 10)/(9,999 × 10)
4.31046 = 431,003/99,990
3. Reduce (simplify) the fraction above:
431,003/99,990
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).
431,003 = 293 × 1,471
99,990 = 2 × 32 × 5 × 11 × 101
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 (293 × 1,471; 2 × 32 × 5 × 11 × 101) = 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.
431,003 ÷ 99,990 = 4, remainder = 31,043 ⇒
431,003 = 4 × 99,990 + 31,043 ⇒
431,003/99,990 =
(4 × 99,990 + 31,043) / 99,990 =
(4 × 99,990) / 99,990 + 31,043/99,990 =
4 + 31,043/99,990 =
4 31,043/99,990
