Question from Alexia, a student:

I am having real trouble with how to order 18/11 , 2/5 , 6/15 from least to greatest can you give me a step by step real easy way to do it?

Hi Alexia,

First notice that 3 divides the numerator and denominator of 6/15 so 6/15 = 2/5. Hence your second and third fractions are equal. Hence you are left with ordering 18/11 and 2/5.

The numerator of the fraction 18/11 is larger than the denominator. What does that mean? which is larger, 18/11 or 2/5?

I hope this helps,
