i have tens ones and tenths.my digits are next door numbers and they add up to9 what number am i

To find the value of the number you are describing, let's break down the information given.

You have tens, ones, and tenths. From this, we can deduce that the number you are referring to is a decimal number.

The digits are next-door numbers, which means they are consecutive integers. In other words, they are neighbors in numerical order.

Additionally, their sum is 9.

To solve this, we need to find two consecutive numbers that add up to 9. Let's explore the possibilities:

1) Let's assume the tens digit is smaller and the ones digit is larger. If the tens digit is 2, then the ones digit would be 2 + 1 = 3. That would make the number 2.3, but the sum of the digits is only 5 (2 + 3 = 5). This is not our answer.

2) If we assume that the tens digit is larger and the ones digit is smaller, then the sum of the digits would be the smaller digit plus the larger digit, which is equal to 9. This is a more likely scenario.

Let's try with the tens digit as 3: if the tens digit is 3, then the ones digit would be 3 - 1 = 2. This gives us the number 3.2. When we add the digits 3 + 2, we get the sum of 5. Again, this is not the correct answer.

3) If we assume the tens digit is 4, then the ones digit would be 4 - 1 = 3. This gives us the number 4.3. Checking the sum of the digits (4 + 3) gives us a sum of 7. This is still not our answer.

4) Finally, if we assume the tens digit is 5, then the ones digit would be 5 - 1 = 4. This gives us the number 5.4. And when we add the digits (5 + 4), we get the sum of 9. This is the solution!

Hence, the number you are describing is 5.4.
