Question

round of to the nearest10. 16​

Answer 1

Remember, we did not necessarily round up or down, but to the ten that is nearest to 16. When rounding to the nearest ten, like we did with 16 above, we use the following rules:

A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.

B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.

C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.
