Answer :

To determine the result of increasing 550000 by one thousandth of itself, let's break it down step-by-step:

Step 1: Identify the initial value.
- The initial value is 550000.

Step 2: Determine one thousandth of the initial value.
- One thousandth of 550000 is found by dividing 550000 by 1000.

Step 3: Calculate the increase amount.
- When you divide 550000 by 1000, you get 550.

Step 4: Add the increase amount to the initial value.
- The initial value is 550000, and the increase amount is 550.

Step 5: Perform the addition.
- When you add 550 to 550000, you get 550550.

Thus, increasing 550000 by one thousandth of itself results in an increase amount of 550 and a final value of 550550.
