Question

A class voted for either rollerblading, swimming, or biking as their favorite

summer activity. If rollerblading got 14% percent of the vote and swimming
got 31%, what percentage of the class voted for biking?
Help

Answer 1

The answer is 55%.

Explanation:

This problem involves subtraction and addition.

First you need to add the percent rollerblading got (14%) to the percent swimming got (31%).

When you're finished you should have 45%.

Now you subtract that from 100%.

Now you should have 55%.

So the answer is that 55% of the class voted for biking.

Further Explanation:

Subtraction is when you find the difference, or how much you have left, when a number of something is taken away from the total.

Addition is when you find the sum, or how much you have in all, when a number is add to your total.
