Ray Of Light [21]
<h3>Total approximately 16 boxes of flooring will be needed in Stanley's living room. </h3>

Step-by-step explanation:

Here the given question is <u>incomplete</u>.

Stanley is having wood flooring installed in his living room. The installer has used 10 1/2 boxes of flooring on 2/3 of the room. How many total boxes of flooring will be needed for Stanley's living room?

The number of boxes used in the two third of room = 10 (\frac{1}{2} )   = 10.5 boxes

So, (\frac{2}{3} ) room  =   10. 5 boxes

So, 1 room  = 10.5 \times (\frac{3}{2} )  = 15.75 \approx 16

So, total approximately 16 boxes of flooring will be needed in Stanley's living room.
