To find the average weight, you need to add all of the numbers and then divide them I'll start off by doing this: 1/8+1/8 = 2/8 1/4+1/4+1/4+1/4 = 1 3/8+3/8 = 6/8 1/2+1/2 = 1 then I'll add them together: 2/8+6/8 = 1 1 + 1 + 1 =3 now we need to divide the amount of numbers. the amount of sandwiches weighted (10) will have to be divided therefore, we get 3/10. because this can't be simplified, this will be your final answer.
