Answer:
-26.52
Step-by-step explanation:
I believe you meant (3.4)(-7.8).
As one of these factors is + and the other is -, the product will be -.
Then the product is -(3.4)(7.8), or approx -3(8), or -24.
Rewriting -(3.4)(7.8) in terms of the equivalent improper fractions, we get
-34 78 12652
----- * ----- = ------------- This may also be written as -26.52.
10 10 100
