2. Write the number as an improper fraction.
- 101.694 can be written as an improper fraction.
- An improper fraction = the numerator is larger than or equal to the denominator..
Write down the number divided by 1, as a fraction:
101.694 = 101.694/1
Turn the top number into a whole number.
- Multiply both the top and the bottom by the same number.
- This number is: 1,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
101.694/1 =
(101.694 × 1,000)/(1 × 1,000) =
101,694/1,000
3. Reduce (simplify) the fraction above:
101,694/1,000
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).
101,694 = 2 × 3 × 17 × 997
1,000 = 23 × 53
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (2 × 3 × 17 × 997; 23 × 53) = 2
Divide both the numerator and the denominator by their GCF.
101,694/1,000 =
(2 × 3 × 17 × 997)/(23 × 53) =
((2 × 3 × 17 × 997) ÷ 2) / ((23 × 53) ÷ 2) =
(3 × 17 × 997)/(22 × 53) =
50,847/500
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.
50,847 ÷ 500 = 101, remainder = 347 ⇒
50,847 = 101 × 500 + 347 ⇒
50,847/500 =
(101 × 500 + 347) / 500 =
(101 × 500) / 500 + 347/500 =
101 + 347/500 =
101 347/500
