Question

20.37154878746336 Rounded to the nearest whole number

Answer 1

The answer is 20, because in the 3 in the tenths place is not greater than 5, therefore not allowing 20 to go up to 21. All the other numbers are not needed since you are only rounding to the nearest whole number.

Answer 2

It will be 20 because if the number next to it is 5 and above you will raise it to 21, but if the number is 4 or less, you don’t do anything. So therefore, the answer will be 20.
