3/5 is less than 3/3.
One way you could figure this out is to to do the criss cross method. For example, you would take the denominater of 3/5 (5), and times it by the numerator for 3/3 (3) This makes it 5x3 which is 15, so 3/3 is 15. Next, you do the same thing, but just do the denominator of 3/3 (3) and times it by the numerator of 3/5 (3) and get 9. Now we know that 3/3 will be more than 3/5.
