How would the information about grade and frequency change if there were twice as many of each grade?

Grade Frequency

A 2

B 8

C 11

D 2

F 1

I think that the grades would double if there was twice as many. Thanks.

You are wrong. You didn't answer the frequency part.

What is the difference between 2/15 and 4/30?

The difference between 2/15 and 4/30 is .133333333. Where did you come up with 2/15 and 4/30? I'm confused now.

How would I go about answering the frequency part?

How did you get the difference between 2/15 and 4/30 as .1333 repeating? 4/30 = 2/15

Consider that if there were twice as many of each grade, the total would be twice as great, but so would the number of grades. So the average would be the same.

Is this answer correct? Just double each number. The "frequency" establishes a percentage breakdown ( unless something else changes ) would stay the same no matter how many grades there are. With every grade doubling, the percentage breakdown stays the same.
