Convert 11.969 into equivalent fractions and write it as a percentage value
1. Write the number as a percentage.
- Multiply the number by 100/100
- Note: 100/100 = 1
- The value of the number does not change when multiplying by 100/100
11.969 =
11.969 × 100/100 =
(11.969 × 100)/100 =
1,196.9/100 =
1,196.9%
- In other words:
- Multiply the number by 100...
- ... And then add the percent sign, %
- 11.969 = 1,196.9%
2. Write the number as an improper fraction.
- 11.969 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:
11.969 = 11.969/1
Turn the top number into a whole number.
- Multiply both the top and the bottom by the same number.
- This number is: 1,000.
- 1 followed by as many 0-s as the number of digits after the decimal point.
11.969/1 =
(11.969 × 1,000)/(1 × 1,000) =
11,969/1,000
3. Reduce (simplify) the fraction above:
11,969/1,000
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).
11,969 is a prime number, it cannot be factored into other prime factors
1,000 = 23 × 53
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
But, the numerator and the denominator have no common factors.
GCF (11,969; 23 × 53) = 1
The numerator and the denominator are coprime numbers (no common prime factors, GCF = 1). So, the fraction cannot be reduced (simplified): irreducible fraction.
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.
11,969 ÷ 1,000 = 11, remainder = 969 ⇒
11,969 = 11 × 1,000 + 969 ⇒
11,969/1,000 =
(11 × 1,000 + 969) / 1,000 =
(11 × 1,000) / 1,000 + 969/1,000 =
11 + 969/1,000 =
11 969/1,000
