How do i express 11/20 as a percent??
Reptile [31]
So since a percent is out of 100 you would put 11/20 and right an equal sign next to that and the bottom fraction would be x/100. Then you would find the relationship between 100 and 20. 20 times 5 is 100 so then 11 times 5 is 55. 55% is your answer
