Answer:
3.22
Step-by-step explanation:
When adding in the hundreths group, if there isn't another value, it would just be 2. When adding in the tenths, since both .5 and .7 are above the set value you can keep in the tenths group, you have to carry the excess over. .5+.7= 1.2. These steps would all add up to be 3.22. (.52 + 2.0 + .7) = 3.22
