- 2.9833334 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:
2.9833334 = 2.9833334/1
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.
- 1 followed by as many 0-s as the number of digits after the decimal point.
2.9833334/1 =
(2.9833334 × 10,000,000)/(1 × 10,000,000) =
29,833,334/10,000,000
3. Reduce (simplify) the fraction above:
29,833,334/10,000,000
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).
29,833,334 = 2 × 17 × 89 × 9,859
10,000,000 = 27 × 57
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (2 × 17 × 89 × 9,859; 27 × 57) = 2
Divide both the numerator and the denominator by their GCF.
29,833,334/10,000,000 =
(2 × 17 × 89 × 9,859)/(27 × 57) =
((2 × 17 × 89 × 9,859) ÷ 2) / ((27 × 57) ÷ 2) =
(17 × 89 × 9,859)/(26 × 57) =
14,916,667/5,000,000
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.
14,916,667 ÷ 5,000,000 = 2, remainder = 4,916,667 ⇒
14,916,667 = 2 × 5,000,000 + 4,916,667 ⇒
14,916,667/5,000,000 =
(2 × 5,000,000 + 4,916,667) / 5,000,000 =
(2 × 5,000,000) / 5,000,000 + 4,916,667/5,000,000 =
2 + 4,916,667/5,000,000 =
2 4,916,667/5,000,000
