I have 7 hundreds 19 tens 9 ones 9 tenths and 1 hundredth what number am I.

700 + 190 + 9 + 0.9 + 0.01 = ________

To determine the number you have, we need to add the values of each place together.

You have:
7 hundreds = 700 (since 1 hundred equals 100)
19 tens = 190 (since 1 ten equals 10)
9 ones = 9
9 tenths = 0.9 (since 1 tenth equals 0.1)
1 hundredth = 0.01 (since 1 hundredth equals 0.01)

Now, let's add them all together:

700 + 190 + 9 + 0.9 + 0.01 = 899.91

Therefore, the number you have is 899.91.

To determine the number, we need to interpret the given digits correctly. Let's break down the information step by step:

- 7 hundreds mean we have 700 (7 multiplied by 100).
- 19 tens mean we have 190 (19 multiplied by 10).
- 9 ones mean we have 9.
- 9 tenths mean we have 0.9 (since 0.9 is the same as 9 tenths).
- 1 hundredth means we have 0.01 (since 0.01 is the same as 1 hundredth).

Now, let's add these values together to get the final number:

700 + 190 + 9 + 0.9 + 0.01 = 899.91

Therefore, you are the number 899.91.
