To solve this, we need to write two numbers where the value of the digit 9 in the second number is 10 times the value of the digit 9 in the first number.

The value of a digit in a number depends on its place value. For example:

• In the number 90, the value of 9 is $9 \times 10 = 90$.
• In the number 900, the value of 9 is $9 \times 100 = 900$.

Let’s define two numbers:

• The first number: 90, where the value of 9 is $9 \times 10 = 90$.
• The second number: 900, where the value of 9 is $9 \times 100 = 900$.

In this case, the value of the 9 in the second number (900) is exactly 10 times the value of the 9 in the first number (90).

Thus, the two numbers are 90 and 900.
