Answer:

a, b, c, and e

Step-by-step explanation:

Just by looking at the number of minus you can determine whether the product is either positive or negative. If there is an even number of minus then the product will be positive, and if there is an uneven number of minus, the product will be negative.

negative * negative=positive

negative*positive=negative

positive * positive=positive

For example A.-

(4)(-0.5)(8)(-2/4)

Cancel the common factor of 4.

Move the leading negative in -2/4 into the numerator.

4((-0.5)*(8))-2/4

then cancel the common factor which in that case is 4.

now we are left with.

(-0.5) * (8) * -2

Multiply. -0.5 * 8=-4

-4 * -2=8
