2. Write the number as an improper fraction.
- 1.047244095 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:
1.047244095 = 1.047244095/1
Turn the top number into a whole number.
- Multiply both the top and the bottom by the same number.
- This number is: 1,000,000,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
1.047244095/1 =
(1.047244095 × 1,000,000,000)/(1 × 1,000,000,000) =
1,047,244,095/1,000,000,000
3. Reduce (simplify) the fraction above:
1,047,244,095/1,000,000,000
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).
1,047,244,095 = 32 × 5 × 23,272,091
1,000,000,000 = 29 × 59
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (32 × 5 × 23,272,091; 29 × 59) = 5
Divide both the numerator and the denominator by their GCF.
1,047,244,095/1,000,000,000 =
(32 × 5 × 23,272,091)/(29 × 59) =
((32 × 5 × 23,272,091) ÷ 5) / ((29 × 59) ÷ 5) =
(32 × 23,272,091)/(29 × 58) =
209,448,819/200,000,000
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.
209,448,819 ÷ 200,000,000 = 1, remainder = 9,448,819 ⇒
209,448,819 = 1 × 200,000,000 + 9,448,819 ⇒
209,448,819/200,000,000 =
(1 × 200,000,000 + 9,448,819) / 200,000,000 =
(1 × 200,000,000) / 200,000,000 + 9,448,819/200,000,000 =
1 + 9,448,819/200,000,000 =
1 9,448,819/200,000,000
