First, let's figure out how many feet this makes, and then convert it into yards:
#2 + 2 = 4# #"feet"#
There are #4# feet. How many yards is that? Well, groups of three feet make one yard, so how many groups of three does #4# have? That will tell use how many yards are in #4# ft.
#"3 feet = 1 yard"#
Divide #4/3# to find how many groups of three without going over we can make out of four:
#4/3 = "1 r1"# (1 with a remainder of 1)
There is only #1# full yard that can be made of #4# feet, with one foot remaining, or:
#"4 feet = 1 yard, 1 foot"#
