First, u need to add 6,728 and 5,843 together which is 12,571 then u need to find the nearest hundred which is the 5 hope that helped!
as we move down the list as we push the *digits* to the *left*through the decimal *point* *each* *number has been 10*. and so we can easily *multiply* or divide by *a* power of *10* because of our system of positional numeration. Each Place belongs to the next power of *10*.
