What is the solution to the expression 9 x 9/9 + 9 - 9/9?

To solve the expression (9 \times \frac{9}{9} + 9 - \frac{9}{9}), we can break it down step-by-step.

First, simplify the fraction (\frac{9}{9}). Since 9 divided by 9 equals 1, we can rewrite the expression:

[

9 \times 1 + 9 - 1

]

Now we can simplify it further:

• The first term simplifies to (9).

• The second term remains (9).

• The last term simplifies to (1).

Now, substituting these values back into the expression gives us:

[

9 + 9 - 1

]

Next, we perform the addition and subtraction in order from left to right:

1. Add (9 + 9) which equals (18).

2. Then subtract (1) from (18), which results in (17).

Therefore, the final solution to the expression is (17), confirming that the correct answer is indeed the one noted.
