In a multi-digit whole number, each place value is

**ten times greater** than the place value to its right.

So, a digit in one place represents **ten times**

what it represents in the place to its right.

The 9 in the tens place has a value of 90.

The 9 in the ones place has a value of 9.

So, 90 is ten times greater than 9.

This means that the 9 in the tens place is ten times greater than the 9 in the ones place.
