Average is the total of x divide by number of x. Here, we have, x = 55, 64, 60, 61 number of x = 4 Total of x = 55 + 64 + 60 + 61 = 240 So, the average is, 240 / 4 = 60
your answer will be 64 because u have to add all four numbers up and divide by how many numbers there was and therefore there were 4 numbers and u get 64
