Question

Which expression will produce a negative product?

(0.5)(–0.5)(3.2)(7.9)(–2.4)


(-0.5)(–0.5)(3.2)(-7.9)(-2.4)


(0.5)(–0.5)(3.2)(–7.9)(–2.4)


(0.5)(–0.5)(3.2)(–7.9)(–2.4)(0)

Answer 1

The trick for this problem is knowing that 2 negatives make a positive.

There are 2 negatives in the first expression. We already know it will be positive.

The second expression has 4 negatives. 2 and 2 means it will be positive.

The third expression will produce a negative product.

The fourth expression since multiplied by 0 in the end will equal 0 no matter what.

Hope this helps!
