Question

What is the product? (3.4)(-7.8
a.-26.52
b.11.2
c.-11.2
d.-21

Answer 1

-26.52

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.
