Question

Eva wants to make two pieces of pottery. She needs 3/5 pounds of clay for one piece and 7/10 pounds of clay for the other. She has three bags of clay that weigh 4/5 pounds each. How many bags of clay will she need to make both pieces of pottery? How many bags of clay y she have leftover?

Answer 1

 3/5 + 7/10 = 6/10 + 7/10 = 13/10 = 1 and 3/10 lbs. needed 

She has 4/5 *3/1 bags = 12/5 = 2 and 2/5 pounds 

2 2/5 - 1 3/10 = 2 4/10 - 1 3/10 = 1 and 1/10 pounds left over

Hope I helped:P
