Answer:
-16/3
Step-by-step explanation:
First, you will need to make both of the denominators the same number. Lucky for you, 3 and 15 both have the GCF of 3. To get 15 from 3, you will need to multiply 3 by 5.
When you multiply the denominator of -2/3 by 5, you will have to do the same to the top. Therefore, you will have to multiply -2 by 5 as well.
Now, you are left with 8/15 (-10/15).
Now that the denominators are the same, you can multiply. You only multiply the numerator, the denominator stays the same (15). 8 * -10 = -80.
You've been left with -80/15, but it's not in it's simplest form. You can easily divide the numerator and denominator by 5. The numerator is now -16. The denominator is now 3.
Your answer is -16/3 because you cannot simplify further.
