Is 6/11 greater than or less than or equal to 9/10

Answers

less just cross mutiply it helps me out alot to do that Update: sorry I did that wrong I think it is greater than actually

Normally to compare 2 fractions, I would say to find a common denominator so you can compare them directly, however on this problem we can just use a little common sense to figure it out...

Look at 6/11. 6 is approximately half of 11 so 6/11 is approximately 1/2. Now look at 9/10. If 10/10 is one whole, 9/10 is approximately 1.

So you can look and see that 6/11 < 9/10 because 1/2 < 1
