-7/9 x 144 vbnbvcrxecvbnbvtcrxercvb
Juli2301 [7.4K]
The first step to solving this expression is to reduce the numbers with 9.
-7 × 16
Now we need to multiply the two numbers together using the Rules of Signs for Multiplication. They state that multiplying a negative and a positive equals a negative: (-) × (+) - (-). Keeping this in mind,, when you multiply the two numbers together you should get -112.
Let me know if you have any further questions
