Explain please with details
lesya [120]

Answer:

Step-by-step explanation:

She has 36 yards of material.

She needs 1 1/3 + 1/6 for each place setting

1/3 + 1/6 = 1/2

She needs 1 1/2 yards of material for each setting

1 1/2 = 1.5

She has to divide 36 by 1.5. If there is anything left over, it becomes scrap to be used for her next project.

You can use the following formula

  • # settings = Total material/setting length
  • # settings = 36/1.5 = 24

She can make 24 settings with nothing left over.
