To solve \(10 \text{ tens} - 1 \text{ ten} - 1 \text{ tenth}\):

1. Convert everything into a common unit. One **ten** equals 10, and one **tenth** is \(0.1\).

2. **10 tens** equals \(10 \times 10 = 100\).

3. **1 ten** equals \(1 \times 10 = 10\).

4. **1 tenth** is \(0.1\).

Now calculate the expression:

\[
100 - 10 - 0.1 = 90 - 0.1 = 89.9
\]

Thus, \(10 \text{ tens} - 1 \text{ ten} - 1 \text{ tenth} = 89.9\).
