Suppose u want to place 1,000,000 pennies in large coin banks. If u put 50,000 pennies in each bank in witch bank would u find the 678,230th penny

See the Related Questions below.

every two banks hold 100,000 pennies
so, 12 banks hold 600,000 pennies
13 banks hold 650,000
so, the 14th bank holds all pennies from 650,001700,000
Or, just divide:
678230/50000 = 13.56
That means that it takes more than 13 banks, but less than 14. So, the 14th bank is the one that gets the penny in question.
