In a grid-in question, what must you remember about units or decimals?

• A. Include units in parentheses
• B. Provide the numerical value with the correct decimal places
• C. Use fractions only
• D. Write in scientific notation

Answer: (B)

In grid-in questions, you enter only the numerical value with the decimal placed to match the required precision. Units aren’t written in the grid, and you don’t use fractions or scientific notation unless the problem explicitly allows them. The number of digits after the decimal is set by the question’s instruction: if you’re told to give the answer to the nearest tenth, include one decimal place; to the nearest hundredth, include two decimal places, and so on. So the best approach is to provide the numerical value with the correct decimal places to reflect the intended precision of the answer.
