The digit in a number that has a greater value than ten times the value of the first digit to its right is the digit in the tens place or higher. For example, in the number 52, the digit 5 (in the tens place) has a value of 50, which is greater than ten times the value of the digit 2 (which is 20). Thus, any digit in a higher place value can potentially meet this criterion.
In the number 123456789000, the digit in the ten billions place is 1. The ten billions place is the first digit to the left of the billions place, which is represented by the digit 2 in this case. Therefore, 1 is the digit that occupies the ten billions place.
Any multiple of ten ends with the digit 0.
