Step-by-step explanation:

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!
