Question

Jan began with 5/6 pound of modeling clay she used 1/5 of the clay to make decorative magnets. She divided the remaining clay into 8 equal portions what is weight of the clay in each portion?

Answer 1

Starting weight:  5/6 lb.  Of this, Jan used 1/5, which would be (1/5)(5/6) lb, 
or 1/6 lb, leaving 4/6 lb, or 2/3 lb. unused.

                                                       2/3 lb
Now divide 2/3 lb by 8 portions:  ----------------- = (2/24) lb/portion, or 
                                                       8 portions

1/12 lb/portion.
