Convert 11.01 into equivalent fractions and write it as a percentage value
1. Write the mixed repeating (recurring) decimal number as a percentage.
Approximate to the desired number of decimal places (14).
11.01 ≈ 11.01111111111111
Multiply the number by 100/100.
- The value of the number does not change when multiplying by 100/100.
- Note: 100/100 = 1
11.01111111111111 =
11.01111111111111 × 100/100 =
(11.01111111111111 × 100)/100 =
1,101.111111111111/100 =
1,101.111111111111% ≈
1,101.11%
(rounded off to max. 2 decimal places)
- In other words:
- Approximate to the desired number of decimal places...
- Multiply the number by 100...
- ... And then add the percent sign, %
- 11.01 ≈ 1,101.11%
2. Write the mixed repeating (recurring) decimal number as an improper fraction.
11.01 can be written as an improper fraction.
- The numerator is larger than or equal to the denominator.
Set up the first equation.
- Let y equal the decimal number:
y = 11.01
Set up the second equation.
- Number of decimal places repeating: 1
Multiply both sides of the first equation by 101 = 10
y = 11.01
10 × y = 10 × 11.01
10 × y = 110.1
Get the same number of decimal places as for y:
10 × y = 110.11
Note: 110.11 = 110.1
Subtract the first equation from the second one.
- Having the same number of decimal places ...
- The repeating pattern drops off by subtracting the two equations.
10 × y - y = 110.11 - 11.01 ⇒
(10 - 1) × y = 110.11 - 11.01 ⇒
We now have a new equation:
9 × y = 99.1
Solve for y in the new equation.
9 × y = 99.1 ⇒
y = 99.1/9
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 11.01
According to our calculations:
y = 99.1/9
⇒ 11.01 = 99.1/9
Get rid of the decimal places in the fraction above.
- Multiply the top and the bottom number by 10.
- 1 followed by as many 0-s as the number of digits after the decimal point.
11.01 = (99.1 × 10)/(9 × 10)
11.01 = 991/90
3. Reduce (simplify) the fraction above:
991/90
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).
991 is a prime number, it cannot be factored into other prime factors
90 = 2 × 32 × 5
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 (991; 2 × 32 × 5) = 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.
991 ÷ 90 = 11, remainder = 1 ⇒
991 = 11 × 90 + 1 ⇒
991/90 =
(11 × 90 + 1) / 90 =
(11 × 90) / 90 + 1/90 =
11 + 1/90 =
11 1/90
991/90 ~ Equivalent fractions.
- The above fraction cannot be reduced.
- That is, it has the smallest possible numerator and denominator.
By expanding it we can build up equivalent fractions.
Multiply the numerator & the denominator by the same number.
Example 1. By expanding the fraction by 3.
991/90 = (991 × 3)/(90 × 3) = 2,973/270
Example 2. By expanding the fraction by 7.
991/90 = (991 × 7)/(90 × 7) = 6,937/630
- Of course, the above fractions are reducing...
- ... to the initial fraction: 991/90
:: Final answer ::
Written in 4 different ways
As a reduced (simplified) positive improper fraction:
11.01 = 991/90
As a mixed number:
11.01 = 11 1/90
As a percentage:
11.01 ≈ 1,101.11%
As equivalent fractions:
11.01 = 991/90 = 2,973/270 = 6,937/630
