Question

Because all of the amounts end with 0, it appears that they are rounded to the nearest million dollars, so it would make sense to round the results to the nearest million dollars. True or false?

Answer 1

False. Rounding to the nearest million dollars would not be appropriate in this case.

Step-by-step explanation:

False. Rounding to the nearest million dollars would not be appropriate in this case.

When considering rounding, it is important to look at the significance of the digits. In this case, all the amounts end with 0, which might make it seem like rounding to the nearest million dollars is logical.

However, it is crucial to consider the significance of trailing zeros in a number with a decimal point. Rule 5 states that trailing zeros are significant, regardless of whether they occur before or after the decimal point. Therefore, rounding to the nearest million dollars would not be accurate.

For example, if we have $18,990,000 and round to the nearest million dollars, we would get $19,000,000. However, this would not be correct because the trailing zero is significant. The more accurate rounded value would be $19,000,000.
