What is 623 rounded to the nearest tens place?

To determine what 623 rounds to in the nearest tens place, we first identify the tens and ones digits in the number. The tens digit in 623 is 2, and the ones digit is 3.

When rounding to the nearest tens, you consider the digit in the ones place. The general rule for rounding is that if the digit in the ones place is 5 or greater, you round up the tens digit by one. Conversely, if it is less than 5, you keep the tens digit the same.

In this case, since the ones digit is 3, which is less than 5, we do not round up. Therefore, we keep the tens digit (2) the same and convert the ones digit to 0, resulting in 620.

Thus, rounding 623 to the nearest tens place gives us 620, making it the correct answer.
