3/4 of the tables were removed from the cafeteria today. 40 students need to sit in the remaining tables. How much of the original table seating does each student have available to them now?

10 tables

Step-by-step explanation:

3/4*40= 10

63.8%

Step-by-step explanation:

We see that the total number of people sampled was 1000.

Out of those 1000 people, 638 of them wore glasses.

Taking the percent means diving the part by the whole (part/whole), so:

638/1000 = 63.8%

Thus, we predict that about 63.8% of Americans would wear glasses.

Hope this helps!
