Question

Which of the following is the smallest whole number that gets rounded off to 500 when we round off the numbers to the nearest hundred?

• A. 550
• B. 440
• C. 450
• D. 540

Answer 1

The correct option is C 450

Let’s check all the options using a number hill.

Placing 440 and 450 on the number hill and rounding the numbers to the nearest hundred, we can see that 440 rounds down to 400 and 450 rounds up to 500.

Placing 540 and 550 on the number hill and rounding off the numbers to the nearest hundred, we can see that 540 rounds down to 500 and 550 rounds up to 600.

Of the four options, only 450 and 540 round off to 500.

Therefore, 450 is the smallest whole number that will round off to 500.
