How do you order the following from least to greatest #1.9, 2sqrt(11/4), sqrt5, 3 5/6#?
Quite a neat way of deciding on the order without using a calculator to find the exact values, is to square each term to get rid of the square roots.
We can also just work with approximations, as the numbers are quite different in size
The squares in ascending order are
So the correct order of the original numbers is
