So to find the missing value when you have a number and a number is simple all you have to do is percent/ 100 = a/b then you multiply the two numbers across from each other and divide by the lonely number so 18/100=27/x so multiply 27x100=2700 then divide by 18 so 2700/18= 150 so x= 150 for the second one you do the same thing 36/100=45/y do 45x100=4500 then divide by 36 4500/36=125 so y=125 and to check you can always do 45/125 x100 and you should get the same percentage
