hi im having trouble on my math homework please show work

So the fraction form of 65% is 65/100, both the top and buttom number of the fraction can be divided by 5. So i divided both by 5 and got 13/20, 13 is only a product of 1X13 so we know 13 cannot be further divided, and 20 and 13 share no common factors so your answer is 13/20/
