2. Write the number as an improper fraction.
- 44.8832 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:
44.8832 = 44.8832/1
Turn the top number into a whole number.
- Multiply both the top and the bottom by the same number.
- This number is: 10,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
44.8832/1 =
(44.8832 × 10,000)/(1 × 10,000) =
448,832/10,000
3. Reduce (simplify) the fraction above:
448,832/10,000
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).
448,832 = 26 × 7,013
10,000 = 24 × 54
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (26 × 7,013; 24 × 54) = 24
Divide both the numerator and the denominator by their GCF.
448,832/10,000 =
(26 × 7,013)/(24 × 54) =
((26 × 7,013) ÷ 24) / ((24 × 54) ÷ 24) =
(22 × 7,013)/54 =
28,052/625
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.
28,052 ÷ 625 = 44, remainder = 552 ⇒
28,052 = 44 × 625 + 552 ⇒
28,052/625 =
(44 × 625 + 552) / 625 =
(44 × 625) / 625 + 552/625 =
44 + 552/625 =
44 552/625
