Question

Round to the nearest million 123,045,067

Answer 1

Answer:

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.

Answer 2

We know that the millions digit is the seventh digit at the left of the decimal point.

Our number rounded to the nearest million is:

123,045,067 ≈ 123,000,000

Now let's see how to find this:

In our number:

123,045,067

The millions digit is a 3, and underlining that digit we get:

123,045,067

Now we want to round to the nearest million, this means that we need to look at the digit that is just at the right of it.

If that digit is 5 or more, we round up, adding 1 to the millions digit and filling with zeros the right part of the number.

If that digit is smaller than 5, we round down, just filling with zeros the right part.

For our number, 123,045,067, the digit at the right is zero, this means that we need to round down.

Then our number rounded to the nearest million is:

123,045,067 ≈ 123,000,000
