Question

Rounding off 43 to nearest ten will give us ____.

• A. 40
• B. 50
• C. 60
• D. 45

Answer 1

The correct option is A 40

To round off 43 to the nearest ten, we find the multiples of 10 that are close to 43, which are 40 or 50.

We check the digit in the ones place. If the digit is 5 or greater than 5, we round up to the higher value which is 50 in this case.

But when the digit in the ones place (3) is less than 5 as in this case, we round it down to 40.

We can also see from the number line above that 43 is closer to 40 than 50.
