without dividing you can still see that you're dividing the number 5 1/6 into more small pieces when you divide by 3 5/8 than when dividing by 2 2/5. it's like how you know that dividing 100 by 3 is going to give you a smaller number than dividing it by 2 because when you divide 100 by 3 the groups will have smaller numbers because there are more groups.
