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.
The answer is the first solution...hope this helped?

Answer: 78.6</h3>
Work Shown:
Multiply across the rows to form a third column. Example: 9*90 = 810 in the first row.
The values in the third column add to 810+1440+1050 = 3300
Divide this over the total number of people which is 9+18+15 = 42
The mean is 3300/42 =78.571 approximately which rounds to 78.6
Ok, It's hard to explain so I'll use an example.
1/5 + 2/15
now you try to find a number that goes into both for this example it would be 3
3*5=15 and then that equals the 2/15
so you then multiply 3 by the numerator getting the fraction
3/15 + 2/15
with the answer of
5/15 which can be reduced to
1/3
