Answer 1

To simplify the expression \((-3.5) \times (-0.45)\), we can follow the rule that multiplying two negative numbers results in a positive number.

First, we can multiply the absolute values:

\[ 3.5 \times 0.45 \]

Now, we can perform the multiplication:

\[ 3.5 \times 0.45 = 1.575 \]

Since we are multiplying two negative numbers, the result is positive:

\[ (-3.5) \times (-0.45) = 1.575 \]

Thus, the simplified expression is:

\[ \boxed{1.575} \]
