Final answer:
0.005 rounded to the nearest whole number is 0, as the first digit after the decimal is less than 5, which means you round down.
Step-by-step explanation:
The question asks to round 0.005 to the nearest whole number. When rounding a number to the nearest whole number, you look at the first digit after the decimal point. If this digit is 5 or greater, you would round up. If it is less than 5, you round down.
In this case, the first digit after the decimal in 0.005 is a 0, which is less than 5. Therefore, you round down. So, 0.005 rounded to the nearest whole number is 0 (a).
