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 the weight of the clay in each portion

Answer 1

First, you must make common denominators...
5/6 pound = 25/30 pound
1/5 pound = 6/30 pound

Then, you must subtract
25/30 - 6/30 = 19/30

Finally, divide the remainder by 8, or multiply by the reciprocal
19/30 • 1/8 = 19/240
