Question

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

Answer 1

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.
