Yes. For example, the mean of: 10,20,20,20,20,30 is (10+20+20+20+20+30)/6
If you mean: 7/10 then they are 14/20 and 21/30
if by thrity equals you mean straight up 30, then the answer is 10.
10, 10, 20, 30, 30, 50.
10 minus -20 is 30.
10 more than 20 is 30. Not sure what you mean by 10 more of 20.
A mean is an average An example 10 +20 +30 =60 The mean/average of this is 20
20
30-20 = 10
30 or -10 if the 20 is negative.
10
300

The gcf of 20 and 30 means the greatest common factor. You can do this my dividing 20 and 30 by the same number. Eventually, you will get 10, no other number is greater than 10. 20/10 = 2 and 30/10 = 3. So your answer will be 10.
