Example Question #2 : How To Find Percentage
What percent (%) of 50 is 30?
40%
30%
50%
60%
166%
60%
The original number in this problem is 50 and you must find the percentage of 30 from 50.
Another way to view this problem is what percentage of the original 50 equals 30.
Let x equal the percentage:
50(x) = 30
50x = 30
In order to change the decimal 0.6 to a percentage multiply by 100:
0.6 x 100 = 60%
Example Question #6 : How To Find Percentage
There were an estimated 20.5 million registered cars in the United States in 1995. The 15 years later the number of registered cars was an en estimated 25.0 million. What is the percent increase in registered cars from 1995 to 2010 rounded to the nearest whole number?
The formula for the percent increase is:
Substituting the given values into the above equation:
After rounding, the answer is 22%
The other answers represent possible mistakes that could have been made: 18% is the mistake of dividing by the final value, not the initial value; 10% is the mistake of dividing by the sum of the final and the initial values; and 21% is the mistake of improper rounding or not doing the division to the third digit.

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.
