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 piece she has three bags of clay that weighs 4/5 pounds each how many bags of clay would even need to make both pieces of pottery how many pounds of clay will she have left over

Answer 1

I am not sure but depending on my results I think sh3 will have 1/2 left over

Answer 2

3/5 + 7/10 = 6/10 + 7/10 = 13/10...how much clay she needs
3 * 4/5 = 12/5 ...how much clay she has

(13/10) / (4/5) =
13/10 * 5/4 =
65/40 =
1 25/40 reduces to 1 5/8 bags of clay are needed.

12/5 - 65/40 = 96/40 - 65/40 = 31/40.....left-over clay
