This concept is commonly used in many word problem and different calculations. A whole number is a non-decimal number, non-negative number starting from zero. While rounding to the nearest whole number if the number to the right of the rounding number is less the 5 round down and if the number is 5 or more round up.

The number in the thousands place is 3 in 5,673,489. The number to the right of the thousands place 3 is 4 which is less than 5. Replace all the numbers to the right of thousands by zeros. Hence rounding the number is 5,673,000. Question: Multiple choice question (Pick the correct option.) What is 7,549 rounded to nearest tens place? a) 7,548 b) 7,500 c) 7,550 d) None of these. Correct answer: option c. The number in the tens place is 4 in 7,549. The number to the right of the tens place is 9 which is greater than 5. Round the tens place one units up.
