Question: I’m trying to calculate what percentage is 17 out of 20. 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 17 out of 20 in percentage, and how you calculate it.
What is 17/20 in percentage?
Answer: 17 is 85% out of 20.
We have two methods to figure out what is 16/20 in percent, with steps for easy understanding.
Method 1: Long division with remainder
Calculate \( 17:20 \)
- 20 enters into 17,
0 times
, remainder 17Result (ongoing) = 0.
Multiply the remainder by 10 to get 170. Now calculate 170 : 20 - 20 enters into 170,
8 times
, remainder 10Result (ongoing) = 0.8
Multiply the remainder by 10 to get 100. Now calculate 100 : 20 - 20 enters into 100,
5 times
, remainder 0
Remainder = 0, means you're done.Result (final) = 0.85
Now you multiply the reults by 100 \( (0.85 \times 100 = 85 ) \) and you get 85%.
Solution: 17 out of 20 equals 85%.
Method 2: Using fractions
Calculate \( P(\text{%}) = \frac{ 17 }{ 20 } \times 100 \)
We need to get the fraction to be of the type \( \frac{ P }{ 100 } \times 100 \)
In our case we need \( \frac { 17 \times x }{ 20 \times x } \times 100 \)
That means \( 20 \times x = 100 \)
\( x = \frac{100}{ 20 } = 5 \)
Our fraction is now \( \frac { 17 \times 5 }{ 20 \times 5 } \times 100 \)
We know that the denominator \( 20 \times 5 = 100 \) so we construct the fraction again.
\( P = \frac { 17 \times 5 }{100} \times 100 \)
\(= 17 \times 5 \)Since \( 17 \times 5 = 85 \), we have our result
\( P = 85 \).
Solution: 17 out of 20 equals 85%.
