3\4 ! you simply convert 7.5% into a fraction. (move the decimal point to the right two times. This should give you 75. Remember to put 75 over 100. EX: 75/100 Next you must find the greatest common fact of both numbers. In this case the number is 25. 25 goes into 75 3 times. So that is your numerator or the number on top. 25 goes into 100 4 times. This will be your denominator or the number on the bottom. Your answer should be 3/4! Make sure to show your work! good luck!
