### Example Question #1 : How To Find The Whole From The Part With Percentage

If 40 percent of a number is 44, what is 60 percent of the same number?

**Possible Answers:**

**Correct answer:**

To determine what 60 percent of the number is, one must first determine what the number is. To find the number, set up a proportion relating the original percentage and the value of the percentage where the top number is the fractional value and the bottom number is the total.

Use cross multiplication to solve for the number.

Once the number is found, the new percentage can be found. There are two ways to do this: multiplication or a proportion.

- Multiplication:
- Proportion:

This means that 60 percent of the number is 66.
