Convert 36.4 into equivalent fractions and write it as a percentage value
1. Write the pure repeating (recurring) decimal number as a percentage.
Approximate to the desired number of decimal places (14).
Multiply the number by 100/100.
- The value of the number does not change when multiplying by 100/100.
- Note: 100/100 = 1
36.44444444444444 =
36.44444444444444 × 100/100 =
(36.44444444444444 × 100)/100 =
3,644.444444444444/100 =
3,644.444444444444% ≈
3,644.44%
(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, %
- 36.4 ≈ 3,644.44%
2. Write the pure repeating (recurring) decimal number as an improper fraction.
36.4 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 = 36.4
Set up the second equation.
- Number of decimal places repeating: 1
Multiply both sides of the first equation by 101 = 10
y = 36.4
10 × y = 10 × 36.4
10 × y = 364.4
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 = 364.4 - 36.4 ⇒
(10 - 1) × y = 364.4 - 36.4 ⇒
We now have a new equation:
9 × y = 328
Solve for y in the new equation.
9 × y = 328 ⇒
y = 328/9
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 36.4
According to our calculations:
y = 328/9
⇒ 36.4 = 328/9
3. Reduce (simplify) the fraction above:
328/9
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).
328 = 23 × 41
9 = 32
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 (23 × 41; 32) = 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.
328 ÷ 9 = 36, remainder = 4 ⇒
328 = 36 × 9 + 4 ⇒
328/9 =
(36 × 9 + 4) / 9 =
(36 × 9) / 9 + 4/9 =
36 + 4/9 =
36 4/9
328/9 ~ 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 4.
328/9 = (328 × 4)/(9 × 4) = 1,312/36
Example 2. By expanding the fraction by 7.
328/9 = (328 × 7)/(9 × 7) = 2,296/63
- Of course, the above fractions are reducing...
- ... to the initial fraction: 328/9
:: Final answer ::
Written in 4 different ways
As a reduced (simplified) positive improper fraction:
36.4 = 328/9
As a mixed number:
36.4 = 36 4/9
As a percentage:
36.4 ≈ 3,644.44%
As equivalent fractions:
36.4 = 328/9 = 1,312/36 = 2,296/63
