Round to the nearest million 123,045,067

123,000,000

Step-by-step explanation:

When rounding, the number that we look at is the number to the right of what we are rounding to.  When rounding to the nearest million we look at the number to the right which is in the hundred thousandth position.  In this case that is a 0.  In rounding, if the number we are looking at is 0-4 we round down an if the number we are looking at is 5-9 we round up.  Since the number is 0 we will round down.  The nearest million below 123, 045, 067 is 123,000,000.
