To perform the operation \(1.2 \times 10^{-1} - 8.5 \times 10^{-2}\), we first need to express both numbers with the same exponent for the powers of ten.
Let's convert \(8.5 \times 10^{-2}\) to have the same exponent as \(1.2 \times 10^{-1}\):
\[
8.5 \times 10^{-2} = 0.085 \times 10^{-1}
\]
Now we can rewrite the expression:
\[
1.2 \times 10^{-1} - 0.085 \times 10^{-1}
\]
Now we can combine the coefficients:
\[
(1.2 - 0.085) \times 10^{-1} = 1.115 \times 10^{-1}
\]
Thus, the final result is:
\[
\boxed{1.115 \times 10^{-1}}
\] or \(0.1115\).
