<h3>
Answer: 7/20</h3>
============================================================
Explanation:
One large square cake cuts into 4 smaller slices
Since we have 5 such cakes that are cut like this, we have 5*4 = 20 slices all together.
Count the number of dark shaded slices that are shown in the lower diagram. We have 4+3+4+2 = 7+6 = 13 slices of cake that are left over. This must mean the class ate 20-13 = 7 slices.
The fraction of the cakes eaten is 7/20
Notes:
- 7/20 = 35/100 = 0.35 = 35%
- The fraction 7/20 cannot be reduced further because 7 and 20 have no common factors other than 1.

Answer:
4.5 m
Step-by-step explanation:
Distance from center to the the bottom part where headroom begins is 3.9 m-2.6 m=1.3 m
Since the radius is 2.6 m and acts as hypotenuse(see attached image), then the other length will be
Approximately 2.25 m
The half width is 2.25 m hence full width will be 2.25*2=4.5 m
