Question

A forest ranger correctly rounded the number of visitors to a park to be 120,000 visitors. Write a number that could be the actual number of visitors if he roundedto the nearest ten thousand.

Answer 1

119,456 or 121,234 visitors.

Explanation:

Rounding works literally by polishing a number. The rule of thumb is to round down when your digit is 5 or less, and if it is 6 or more, round up.

In this case, we look to the tens of thousands place. The polished number is 120,000, so that means he could have rounded up or down. I gave 119 and 121 as answers, because they both round to 120,000!
