2. Write the number as an improper fraction.
- 10.96666666668 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:
10.96666666668 = 10.96666666668/1
Turn the top number into a whole number.
- Multiply both the top and the bottom by the same number.
- This number is: 100,000,000,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
10.96666666668/1 =
(10.96666666668 × 100,000,000,000)/(1 × 100,000,000,000) =
1,096,666,666,668/100,000,000,000
3. Reduce (simplify) the fraction above:
1,096,666,666,668/100,000,000,000
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).
1,096,666,666,668 = 22 × 32 × 67 × 1,699 × 267,611
100,000,000,000 = 211 × 511
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (22 × 32 × 67 × 1,699 × 267,611; 211 × 511) = 22
Divide both the numerator and the denominator by their GCF.
1,096,666,666,668/100,000,000,000 =
(22 × 32 × 67 × 1,699 × 267,611)/(211 × 511) =
((22 × 32 × 67 × 1,699 × 267,611) ÷ 22) / ((211 × 511) ÷ 22) =
(32 × 67 × 1,699 × 267,611)/(29 × 511) =
274,166,666,667/25,000,000,000
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.
274,166,666,667 ÷ 25,000,000,000 = 10, remainder = 24,166,666,667 ⇒
274,166,666,667 = 10 × 25,000,000,000 + 24,166,666,667 ⇒
274,166,666,667/25,000,000,000 =
(10 × 25,000,000,000 + 24,166,666,667) / 25,000,000,000 =
(10 × 25,000,000,000) / 25,000,000,000 + 24,166,666,667/25,000,000,000 =
10 + 24,166,666,667/25,000,000,000 =
10 24,166,666,667/25,000,000,000
