Answer:

-1/240 (Might be wrong though)

Step-by-step explanation:

The first thing we need to do is multiply 1/15 and 1/16 because product means the answer to a multiplication equation.

1/15 times 1/16 = (1*1)/(15*16) = 1/240

Now that we know the product 1/240, we just have to find the opposite, which is -1/240 because you just add a negative sign in opposites( even in negative numbers)

And (2) should be the multiplication property due to multiplying both sides by 2.
