Answer:
568
Explanation:
A whole number is a number without any fractional part; in other words, it does not have any non-zero digits after the decimal point.
When you round a number to the nearest whole number, first look at the digit right after the decimal point;
• if the digit is less than 5, then the nearest whole number is the original number, but without any digit after the decimal point. [rounding down]
• if the digit is 5 or greater than 5, then the nearest whole number is the next whole number (i.e., add 1 to the original number and remove the digits after the decimal point). [rounding up]
