Answer:
The height is 16.
Step-by-step explanation: If you add 8+8 you will notice that it is equal to 16 because 8 is a missing number.
<em><u>The proportion that could be used to solve for the variable is:</u></em>
h = 7.5
<em><u>Solution:</u></em>
Given that,
16 walls in 40 hours 3 walls in h hours
Which means,
16 walls build in 40 hours
Then 3 walls in h hours
We have to write a proportion
The number of walls and the number of hours are proportion
Therefore, we get,
Cross multiply and solve for h
Thus the proportion is solved
