Final answer:

To solve the given expression, start by dividing 7 by -9 and multiplying 7/3 by 10/7. Finally, subtract the two results to find the answer.

Step-by-step explanation:

To solve the expression (7/1 divided by -9) - 7/3 x 10/7, we need to follow the order of operations. First, we solve the division problem: (7/1) divided by -9. This is equal to 7 divided by -9, which simplifies to -7/9. Next, we multiply 7/3 by 10/7, which gives us 70/21. Finally, we subtract -7/9 from 70/21. To do this, we need to find a common denominator, which is 63. The expression simplifies to -49/63, which can be further reduced to -7/9.

So, the answer to the expression (7/1 divided by -9) - 7/3 x 10/7 is -7/9.
