45% of 20 is
plz show your work cuz i dont get it

9, you have to multiply .45 by 20 because .45 is equal to 45%  to get a decimal equal to a percent just put the decimal point two numbers to the left.

45/100 = X/2045 is the percent so that is over 100 (percent is always over 100) equals blank over 20 because IS comes before OF in the alphabet and IS goes on top of OF. then you do 100 divided by 5 equals 20 (divided by 5) do that on top also. 100 ÷ 5 = 20 45 ÷ 5 = 9 ANSWER = 9/20

45 is the only number in both sets
