2. Write the number as an improper fraction.
- 1.1764705888 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:
1.1764705888 = 1.1764705888/1
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.
1.1764705888/1 =
(1.1764705888 × 10,000,000,000)/(1 × 10,000,000,000) =
11,764,705,888/10,000,000,000
3. Reduce (simplify) the fraction above:
11,764,705,888/10,000,000,000
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).
11,764,705,888 = 25 × 13 × 37 × 764,339
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 (25 × 13 × 37 × 764,339; 210 × 510) = 25
Divide both the numerator and the denominator by their GCF.
11,764,705,888/10,000,000,000 =
(25 × 13 × 37 × 764,339)/(210 × 510) =
((25 × 13 × 37 × 764,339) ÷ 25) / ((210 × 510) ÷ 25) =
(13 × 37 × 764,339)/(25 × 510) =
367,647,059/312,500,000
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.
367,647,059 ÷ 312,500,000 = 1, remainder = 55,147,059 ⇒
367,647,059 = 1 × 312,500,000 + 55,147,059 ⇒
367,647,059/312,500,000 =
(1 × 312,500,000 + 55,147,059) / 312,500,000 =
(1 × 312,500,000) / 312,500,000 + 55,147,059/312,500,000 =
1 + 55,147,059/312,500,000 =
1 55,147,059/312,500,000
