Order these fractions 79/7, 11 3/11, 45/4 from least to greatest.

First you have to make the mixed number a fraction and then make denominators all the same. Do you know how to do that?

I'll give you one:

11 3/11 = 124/11

So I think it is 11 3/11, 45/4, then 79/7. Correct?

Nope. Did you change them all to the lowest common denominator?

P.S. With math, you don't "think" anything, no guessing. It's right or wrong.
