What is the sum of one-fifth of 120?
One 5th of the numbers in each column are 2’s, one-fifth are 3’s, and so on to one-fifth are 8’s, So since one-fifth of 120 is 24, the sum of each column is 24* (2+3+5+7+8) = 24* (25) = 600 So there are 600 ten-thousands + 600 thousands + 600 hundreds + 600 tens + 600 ones or 6000000 + 600000 + 60000 + 6000 + 600 ======== 6666600 Edwin
