Question

find the average of the rational numbers 4/5,2/3,5/6​

Answer 1

Answer:

23/30    0r  0.77(=0.7666....)

Step-by-step explanation:

Average of n no. = (sum of no.)/n

  Here,

n = 3

sum of n no. = 4/5 + 2/3 + 5/6

                     = (24 + 20 + 25)/30

                     = 69/30

∴ Average = (69/30)/3

                  = 69/90

                  = 23/30
