- An improper fraction = the numerator is larger than or equal to the denominator..
Write down the number divided by 1, as a fraction:
8.8526683125 = 8.8526683125/1
Turn the top number into a whole number.
- Multiply both the top and the bottom by the same number.
- This number is: 10,000,000,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
8.8526683125/1 =
(8.8526683125 × 10,000,000,000)/(1 × 10,000,000,000) =

3. Reduce (simplify) the fraction above:
88,526,683,125/10,000,000,000
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).
88,526,683,125 = 32 × 54 × 3,847 × 4,091
10,000,000,000 = 210 × 510
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (32 × 54 × 3,847 × 4,091; 210 × 510) = 54
Divide both the numerator and the denominator by their GCF.
88,526,683,125/10,000,000,000 =
(32 × 54 × 3,847 × 4,091)/(210 × 510) =
((32 × 54 × 3,847 × 4,091) ÷ 54) / ((210 × 510) ÷ 54) =
(32 × 3,847 × 4,091)/(210 × 56) =
141,642,693/16,000,000
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.
141,642,693 ÷ 16,000,000 = 8, remainder = 13,642,693 ⇒
141,642,693 = 8 × 16,000,000 + 13,642,693 ⇒
141,642,693/16,000,000 =
(8 × 16,000,000 + 13,642,693) / 16,000,000 =
(8 × 16,000,000) / 16,000,000 + 13,642,693/16,000,000 =
8 + 13,642,693/16,000,000 =
8 13,642,693/16,000,000
