Convert 7.324 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).
Multiply the number by 100/100.
- The value of the number does not change when multiplying by 100/100.
- Note: 100/100 = 1
7.32424242424242 =
7.32424242424242 × 100/100 =
(7.32424242424242 × 100)/100 =
732.424242424242/100 =
732.424242424242% ≈
732.42%
(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, %
- 7.324 ≈ 732.42%
2. Write the mixed repeating (recurring) decimal number as an improper fraction.
7.324 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 = 7.324
Set up the second equation.
- Number of decimal places repeating: 2
Multiply both sides of the first equation by 102 = 100
y = 7.324
100 × y = 100 × 7.324
100 × y = 732.424
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.
100 × y - y = 732.424 - 7.324 ⇒
(100 - 1) × y = 732.424 - 7.324 ⇒
We now have a new equation:
99 × y = 725.1
Solve for y in the new equation.
99 × y = 725.1 ⇒
y = 725.1/99
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 7.324
According to our calculations:
y = 725.1/99
⇒ 7.324 = 725.1/99
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.
7.324 = (725.1 × 10)/(99 × 10)
7.324 = 7,251/990
3. Reduce (simplify) the fraction above:
7,251/990
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).
7,251 = 3 × 2,417
990 = 2 × 32 × 5 × 11
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (3 × 2,417; 2 × 32 × 5 × 11) = 3
Divide both the numerator and the denominator by their GCF.
7,251/990 =
(3 × 2,417)/(2 × 32 × 5 × 11) =
((3 × 2,417) ÷ 3) / ((2 × 32 × 5 × 11) ÷ 3) =
2,417/(2 × 3 × 5 × 11) =
2,417/330
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.
2,417 ÷ 330 = 7, remainder = 107 ⇒
2,417 = 7 × 330 + 107 ⇒
2,417/330 =
(7 × 330 + 107) / 330 =
(7 × 330) / 330 + 107/330 =
7 + 107/330 =
7 107/330
2,417/330 ~ 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 5.
2,417/330 = (2,417 × 5)/(330 × 5) = 12,085/1,650
Example 2. By expanding the fraction by 6.
2,417/330 = (2,417 × 6)/(330 × 6) = 14,502/1,980
- Of course, the above fractions are reducing...
- ... to the initial fraction: 2,417/330
