Question: I’m trying to calculate what percentage is 28 out of 30. How do I do that?

MathBlog: A percent tells us how many parts out of 100 something is. To write a percent as a fraction, just remove the percent symbol and write the number over 100 as the denominator. Below we explain what is 28 out of 30 in percentage, and how you calculate it.

What is 28/30 in percentage?

Answer: 28 is 93.33% out of 30.

We have two methods to figure out what is 28/30 in percent, with steps for easy understanding.

Method 1: Long division with remainder

Calculate \( 28:30 \)

  1. 30 enters into 28, 0 times, remainder 28
    Result (ongoing) = 0.
    Multiply the remainder by 10 to get 280. Now calculate 280 : 30
  2. 30 enters into 280, 9 times, remainder 10
    Result (ongoing) = 0.9
    Multiply the remainder by 10 to get 100. Now calculate 100 : 30
  3. 30 enters into 100, 3 times, remainder 10
    Result (ongoing) = 0.93
    Multiply the remainder by 10 to get 100. Now calculate 100 : 30
  4. 30 enters into 100, 3 times, remainder 10
    Result (ongoing) = 0.933
    Multiply the remainder by 10 to get 100. Now calculate 100 : 30
  5. 30 enters into 100, 3 times, remainder 10
    Result (ongoing) = 0.9333
    Multiply the remainder by 10 to get 100. Now calculate 100 : 30
  6. 30 enters into 100, 3 times, remainder 10
    Result (ongoing) = 0.93333
    Multiply the remainder by 10 to get 100. Now calculate 100 : 30
  7. 30 enters into 100, 3 times, remainder 10
    Result (ongoing) = 0.933333
    Multiply the remainder by 10 to get 100. Now calculate 100 : 30
  8. 30 enters into 100, 3 times, remainder 10
    Result (ongoing) = 0.9333333
    Multiply the remainder by 10 to get 100. Now calculate 100 : 30
  9. 30 enters into 100, 3 times, remainder 10
    Result (ongoing) = 0.93333333
    Multiply the remainder by 10 to get 100. Now calculate 100 : 30
  10. 30 enters into 100, 3 times, remainder 10
    Result (ongoing) = 0.933333333
    Multiply the remainder by 10 to get 100. Now calculate 100 : 30

Now you multiply the reults by 100 \( (0.933333333 \times 100 = 93.333333333333 ) \) and you get 93.333333333333%.

Solution: 28 out of 30 equals 93.333333333333%.

Method 2: Using fractions

Calculate \( P(\text{%}) = \frac{ 28 }{ 30 } \times 100 \)

  1. We need to get the fraction to be of the type \( \frac{ P }{ 100 } \times 100 \)

  2. In our case we need \( \frac { 28 \times x }{ 30 \times x } \times 100 \)

    That means \( 30 \times x = 100 \)

    \( x = \frac{100}{ 30 } = 3.3333333333333 \)

  3. Our fraction is now \( \frac { 28 \times 3.3333333333333 }{ 30 \times 3.3333333333333 } \times 100 \)

  4. We know that the denominator \( 30 \times 3.3333333333333 = 100 \) so we construct the fraction again.

    \( P = \frac { 28 \times 3.3333333333333 }{100} \times 100 \)
    \(= 28 \times 3.3333333333333 \)

  5. Since \( 28 \times 3.3333333333333 = 93.333333333333 \), we have our result
    \( P = 93.333333333333 \).

Solution: 28 out of 30 equals 93.333333333333%.
