Example Question #71 : Decimals And Percentage

If 37% of a pie was consumed, what is the decimal equivalence to how much of the pie is missing?

Possible Answers:

Correct answer:

Explanation:

This problem is simply asking us to convert 37% into its decimal equivalence.

The quickest way to switch between decimals and percentage is by keeping in mind that it is a factor of 100. For instance, decimals may be converted to percents by multiplying by 100 whereas turning percents to decimals would be the opposite operation (division). This is true because by definition, a percentage is a portion of 100. In this case, we are interested in a portion of 37.

Given this information, 

we may convert from percent to decimal. This would require dividing by 100.
