Answer 2

Finding the Four-Digit Numbers

To find the four-digit number that needs to be added to 7 to obtain the smallest five-digit number, we can use the following equation: 4-digit number + 7 = 5-digit number

Similarly, to find the four-digit number that needs to be added to 4 to obtain the largest four-digit number, we can use the equation: 4-digit number + 4 = 4-digit number

Let's calculate these values step by step.

Smallest Five-Digit Number

To find the smallest five-digit number, we need to add 7 to a four-digit number. The smallest five-digit number is 10,000.

So, the four-digit number that needs to be added to 7 to obtain the smallest five-digit number is: 10,000 - 7 = 9,993

Largest Four-Digit Number

To find the largest four-digit number, we need to add 4 to a four-digit number. The largest four-digit number is 9,999.

So, the four-digit number that needs to be added to 4 to obtain the largest four-digit number is: 9,999 - 4 = 9,995

Therefore, the answers are: - To obtain the smallest five-digit number, add 7 to 9,993. - To obtain the largest four-digit number, add 4 to 9,995.
