Answer: Twelve fifth of an Hour
Step-by-step explanation: a whole is represented by 1
1/3=4/5hours
Whole room 1 =4/5 ÷ 1/3

That's twelve fifth of an hour
The largest possible complete design that can be painted on a 24’ x 16’ wall is 252' by 189'
<h3>
Scale drawing</h3>
Scale drawing involves drawing a drawing in a different size and dimension that is proportional to the original dimension
<h3>Dimensions</h3>
The dimensions of the design for the farm scene painting is given as:

The dimensions of the wall is given as:

Convert feet to inches


Divide the dimensions of the wall by the painting to get the scale ratios (k)


Also, we have:


Remove decimal (do not approximate)

By comparison;
21 is less than 24
Multiply 21 by the dimensions of the painting
So, we have:


Hence, the largest possible complete design that can be painted on a 24’ x 16’ wall is 252' by 189'
