Answer: 939,520
Step-by-step explanation: To round 939,515 to the nearest ten, we first find the digit in the rounding place which in this case is the 1 in tens place.
Next, we look at the digit to the right of of the 1 which in this case is 5.
According to the rules of rounding, since the digit to the right of the rounding place is greater than or equal to 5, we round up.
This means that we add 1 to the digit that's in the rounding place so 1 will become 2 and we change all the digits that appear to the right of the rounding place to 0.
So 939,515 rounded to the nearest 10 is 939,520.
