In the number 11,651, which places contain digits where one digit is ten times as great as the other digit

In the number 11,651, we see that 5 digits are there.

1 = 10 thousands place

1 = 1 thousands place

6 = Hundred's place

5 = Ten's place

1 = One's place

Form the above breakup we can see that the 1 in the ten thousands place is ten times the 1 in the thousands place. So the 1 in the ten thousands place is ten times as great as the 1 in the thousands place. This is the main requirement of the question.
