What percent of is ?

**Possible Answers:**

**Correct answer:**

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.
