Answer: 172,370,000
Step-by-step explanation: To round 172,365,022 to the nearest ten thousand, we first find the digit in the rounding place which in this case is the 6 in the ten thousands place.
Next, we look at the digit to the right of the 6 which is 5.
The rules of rounding say that if the digit to the right of the rounding places is less than 5, we round down and if the digit to the right of the rounding place is greater than or equal to 5, we round up.
Since 5 is greater than or equal to 5, we round up.
This means that we add 1 to the 5 in the rounding place to get 7 and all digits to the right of the 7 will become 0.
So 172,265,022 rounded to the nearest ten thousand is 172,370,000.
