67, 000 rounded to the nearest ten thousand is: 70, 000.
EXPLANATION:
As we are rounding the number to the nearest ten thousand, we will look at the thousand digit of the number in order to decide whether to round the number up or down. As the thousand digit is 7, we must round the ten thousand digit up meaning that the 6 would become a 7. Therefore, the answer would be 70, 000.
