How do you order the rational numbers from least to greatest: 3.8, 3.06, 3 1/6, 3 3/4?

Since they all are of the kind "3 plus something" we only look at the "plus something".

Explanation:

And then we try to find a way to compare them.
#0.8=8/10=80/100#
#0.06=6/100#
#3/4=75/100#
The only problem is #1/6# because we can't express that as #100#th's, but we know that it's #=16/96# which is a bit larger, but close to #16/100#

The differences are great enough, so the order is:
#3.06-3 1/6-3 3/4- 3.8#
