So you are comparing 6/9 and 3/5. First, multiply the 6 from the first one and 5 from the second (numbers that cross each other). That would be 30. Then, the the same with the other numbers that cross which is 3 and 9. That would be 27. Think, which is greater? 30 or 27? Point the crocodile mouth < to the greater number that crosses. So 30 goes on the 6/9 side and 27 goes on the 3/5 side. Hope you understand! Sorry, I can tell you answer if you want :)
