Question: I’m trying to calculate what percentage is 39 out of 50. 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 39 out of 50 in percentage, and how you calculate it.

What is 39/50 in percentage?

Answer: 39 is 78% out of 50.

We have two methods to figure it out, with steps for easy understanding.

Method 1: Long division with remainder

Calculate \( 39:50 \)

  1. 50 enters into 39, 0 times, remainder 39
    Result (ongoing) = 0.
    Multiply the remainder by 10 to get 390. Now calculate 390 : 50
  2. 50 enters into 390, 7 times, remainder 40
    Result (ongoing) = 0.7
    Multiply the remainder by 10 to get 400. Now calculate 400 : 50
  3. 50 enters into 400, 8 times, remainder 0
    Remainder = 0, means you're done.
    Result (final) = 0.78

Now you multiply the reults by 100 \( (0.78 \times 100 = 78 ) \) and you get 78%.

Solution: 39 out of 50 equals 78%.

Method 2: Using fractions

Calculate \( P(\text{%}) = \frac{ 39 }{ 50 } \times 100 \)

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

  2. In our case we need \( \frac { 39 \times x }{ 50 \times x } \times 100 \)

    That means \( 50 \times x = 100 \)

    \( x = \frac{100}{ 50 } = 2 \)

  3. Our fraction is now \( \frac { 39 \times 2 }{ 50 \times 2 } \times 100 \)

  4. We know that the denominator \( 50 \times 2 = 100 \) so we construct the fraction again.

    \( P = \frac { 39 \times 2 }{100} \times 100 \)
    \(= 39 \times 2 \)

  5. Since \( 39 \times 2 = 78 \), we have our result
    \( P = 78 \).

Solution: 39 out of 50 equals 78%.
