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%

A school has a parking lot that is 150.23 feet by 135.12 feet. What is the perimeter of the parking lot?
elena-14-01-66 [18.8K]

Answer: 570.70 ft

Step-by-step explanation:

The perimeter is the distance around the entire parking lot.

The measurement of 150.23 ft by 135.12 ft is half of the distance of the lot because it represents just two sides yet there are 4 sides.

The other two sides have the same measurement as this is a rectangle.

The perimeter of the parking lot is:

= (150.23 * 2) + (135.12 * 2)

= 570.70 ft
