To find the average of the given scores...you have to add all the scores and then divide it by the number of scores....



That is...

+Average+=+Sum+of+scores%2F+Number+of+scores

Sum of scores = +100%2F4%2B+90%2F12+%2B+80%2F7+%2B70%2F0+%2B+60%2F1+

Here the fourth score given is +70%2F0it cannot be evaluated because division of zero is not defined.. Please check your question once again
Here for explaining this problem, let me take it as 70%2F10



==>Sum of scores = +25+%2B+7.5+%2B+11.42++%2B70%2F10+%2B+60++

==>Sum of scores = +25+%2B+7.5+%2B+11.42++%2B7++%2B+60++



==>Sum of scores = +110.92+

Number of scores = 5

That is...

Average+=+Sum+of+scores%2F+Number+of+scores

Average+=+110.92%2F5


==> Average = 22.184


Hope you found the explanation useful.
