Finding the Average: Solving Basic Pre-Algebra Problems

[vincentm]

I know this is basic stuff, but I'm barely geting back into school and starting off with a basic math class, so any help would be highly appreciated, i don't want the answers just to be pointed in the right direction.


'what is the average (arithmetic mean) of 8,7,7,5,3,2 and 2'

(a) $$3\frac{4}{7}$$

(b) $$4\frac{5}{6}$$

(c) $$4\frac{6}{7}$$

(d) 5

(e) $$6\frac{4}{5}$$

Just add them all up, and divide by the total number of numbers you have.

so the answer is (c) $$4\frac{6}{7}$$which i got by adding the numbers up which is 34 and dividied by that total which is 7, so 34 divided by 7 is 4 remainder 6 which gives me $$4\frac{6}{7}$$right?
