What is the product in simplest form? is it the second option or no? i legit don't know, .

To multiply fractions you can multiply straight across the top and straight across the bottom

-5*8= -40

-12*13= -156

So the answer is -40/156

-40 and -156 are both divisible by 4, so it can be reduced

If we divide -40 by 4 we get -10

When we divide -156 by 4 we get -39

So the answer in its simplest form is -10/39, making B the correct answer
