Expert's answer

Let's add these numbers3 3/4, 2 1/4, 2, 4 1/2, 5/6,2/3:

3 3/4+ 2 1/4+ 2 + 4 1/2+ 5/6+2/3=11+3/4+1/4+1/2+5/6+2/3=11+(4+2)/4+(5+4)/6=11+3/2+3/2=11+3=14

To find average we should divide the sum of numbers by their amount. We have 6 numbers so average

a=14/6=7/3

3 3/4+ 2 1/4+ 2 + 4 1/2+ 5/6+2/3=11+3/4+1/4+1/2+5/6+2/3=11+(4+2)/4+(5+4)/6=11+3/2+3/2=11+3=14
