1,000,000 is 1 million
look at the previous digit
if it is less than 5 then leave the millions place as is and replace the following digits with zeroes
if it is equal to or greater than 5, add 1 to the millions place and replace the following digits with zeroes
296,386,482
3<5

296,000,000 is rounded
First of all, I find it easiest to write n equation.
3 / 15 x 8 =
Now that we have an equation, we can figure out a solution.
3 / 15 = 5
5 x 8 = 40
So 8 DVD's would cost $40.00.
