6.67 -? I need 2
6.9876 I need 4
1.67890 I need 5
Which are stored in memory as:
6.6699999999999999
6.9875999999999996
1.6789000000000001
or something very similar. Notice all the mantissas are the same length?

Is this just a trivial exercise for you, or are you ultimately planning on doing something with the result?
