8 out of 200 is what percent
kipiarov [429]
Hey there! 

Here are the steps involved in answering this question:

1. Write 8 out of 200 as a fraction which is \frac{8}{200}

2. Turn the fraction into a decimal. To do this, divide the numerator by the denominator. The numerator is the top part of the fraction while the denominator is the bottom part of the fraction.

\frac{8}{200}  = 0.04

3. You get 0.04. Now, turn this into a percent. Move the decimal, 2 places to the right or just multiply the decimal by 100.

0.04 = 4%

The final answer is 4%.

Another way of doing this is to get 100 as a denominator.
Since, percent means, "Out of 100", we have to make the denominator 100.

1.  \frac{8}{200} = 4/100

Just divide each side by 2.

Again, the final answer is, 4%
