Question

Mrs. Lia has 11 pounds of modeling clay. She divides the clay into 1 2 - pound blocks. If Mrs. Lia sets aside 7 of the blocks and gives the rest to the students in her art class, how many 1 2 - pound blocks of clay does Mrs. Lia give to her class?

Answer 1

Assuming she is dividing into 1/2 lb blocks.

15 of the 1/2 lb are given to the class.

Explanation:

She can make 22 of the 1/2 lb blocks out of 11 lbs. If she sets aside 7, then 22-7=15. She has 15 of the 1/2lb blocks left to give to the class.
