Question

Mr. Miles has 7 7/8 pounds of clay to make 3 models. He uses 2 1/10vpounds to make each model. Mr. Miles says he has about 3 pounds of clay left. Is his statement reasonable?

Answer 1

Answer:
Mr. Miles’s statement is NOT reasonable

Explanation:
If Mr. Miles uses 2 1/10 pounds of clay for each model, Mr. Miles will have used a total of 6.3 pounds of clay.
The decimal form of 7 7/8 is 7.875, so 7.875 minus 6.3 will give you the amount of clay Mr. Miles has left over.

7.875 - 6.3 = 1.575

This means that Mr. Miles statement is not reasonable, as he only has about 1.6 pounds of clay left, not 3.
