Final answer:
To format numbers in the given worksheet, they should be set to two decimal places with the US Dollar symbol ($) right-aligned and the decimal points aligned to allow for clarity and consistency in financial data presentation.
Step-by-step explanation:
When working on a worksheet and dealing with financial data, it's essential to format numbers correctly to ensure clarity and precision. The standard format for currency involves aligning the US Dollar symbol ($), the numerical values, and the decimal points. Given the options, the most appropriate way to format the numbers in columns B through E on the Qtr 1 worksheet is to use two decimal places, with the US Dollar symbol ($) right-aligned and the decimal points aligned. This presentation allows for easy comparison of monetary values, is professional, and is the typical format for financial reporting in the United States.
When rounding off a decimal number to a given number of decimal places, the rule of thumb is to round up if the digit to the right of the last decimal place you're keeping is 5 or higher. Hence, if you have 2.6525272 and want to round it to three decimal places, you would end up with 2.653.
If you need to move the decimal point to express a number in scientific notation or to perform multiplication and division, you use zeros as placeholders if there are not enough digits. For instance, multiplying 2.4 by 100 requires that the decimal point be moved two places to the right, resulting in 240.
