Example Question #1381 : Numbers And Operations

What percent of  is

Possible Answers:

Correct answer:

Explanation:

In order to convert numbers to a percent, it is easiest to set up a ratio. 

We know that percent is just per-cent or per-100, another way to write this is to divide the number by 100. 

We would set up the ratio below with x being the number we are looking for: 

To solve this, we can cross multiply, but to make this an easier multiplication we want to reduce any fractions that can be reduced. The 8/40 on the right will reduce to become 1/5. 

Now we cross multiply 5 times x and 1 times 100 to get: 

Dividing both sides by 5 will give us the percent.
