Round 34 to the nearest ten

30

Step-by-step explanation: To round 34 to the nearest ten, first find the digit in the rounding place which in this case is the 3 in the tens place.

Next, look at the digit to the right of the rounding place which in this case is 4. The rules of rounding tell us that if the digit to the right of the rounding place is less than 5, we round down. If the digit to the right of the rounding place is greater than or equal to 5, we round up.

In this problem, since 4 is less 5, we round down.

This means that the digit in the rounding place which in this case is 3 stays the same and we change all digits to the right of the 3 to zero.

So 34 rounded to the nearest ten is 30.
