To find 60 percent of something, we first need to convert 60 percent into a decimal. We do this by dividing 60 percent by one hundred.

This results in the decimal,

Now we will mutiply 300 by 0.60.

Granada High School has a graduating class of 700 seniors. If  of the high school graduates scored above an  on their final exam, and  of the graduated scored above a , how many students scored  or less on their final? 

First, we must find the percentage of seniors that scored below a . To do this we subtract the  and  of students who scored  and above from . This leaves us with a remaining  of graduates who did not score above a  Next, we find out exactly how many students equal  of the graduating class. To do this we multiply the percentage in decimal form, , against the total number of students, .

So .

So,  of the graduating class did not score above a 

To find 3% of anything, convert it into a decimal. 3% as a decimal is 0.03.

Then we can multiply 150 by 0.03 to get an answer of 4.5.

We could also get this in another way.

3% is just .

150 is , and .

To find 15% of anything, just multiply by 0.15, its decimal equivalent.

In this case, 327 times 0.15 is 49.05.

To find the part from the whole given a percentage, we multiply the whole by the decimal equivalent of the percentage. To find this, we divide the percentage by one-hundred:

Therefore,  of  is 

As of the middle of August, Magnus had saved  of his total travel budget. If Magnus has a goal of saving  , how much does he have left to save?

There are two ways to go about doing this, and both of them require you to look for what is actually being asked. The question asks you for how much he has left to save. This means that we are not looking for , we are looking for  of the savings goal. So, the simpler way to solve this is to do the following:

Note, we also could have found  of  and then subtracted that from . Using this method would have yielded the exact same answer as the other method. 

Since  of the human body is water and we are looking for the dry weight, we want to find  of :

If  of the miles Oscar drives being commuter miles, we can determine how many miles that is by multiplying the total number of miles driven by :

We know that 80 multiplied by some percentage, equals 44. Because a percent is number, divided by 100, we can represent this problem mathematically, as follows:

To get  by itself, multiply both sides of the equation by 80. This gives us:

Then, multiply both sides of the equation by 100. This gives us:

Simplify.

Thus, 44 is 55% of 80.

According to a recent poll,  of voters plan on voting for this candiate for president. If there are 175 million voters total, how many will vote for this candiate?

So out of a total of 175 million, (175,000,000), 34% will vote for this candiate. To find that number, change your percent to a decimal and multiply:

So a total of  people will vote for this presidential candiate.
