1. You know that to get the percentage of a number you multiply the number by the percent and divide it by 100. But they are asking you to find the number so you are going to do the opposite: 18 times 100 divided by 60 and you are going to get the number 30 (that's the original number, if you want to check it get 30 multiply it by 60 and divide it by 100 and you are going to get18). Now they are asking you for 90% of the original number so you do 90 times 30 divided by 100 and you get 27 (final answer)
