To solve these expressions, we'll need to follow some basic mathematical rules:

1. (-80%)(-2) = (-80/100)(-2) = 1.6. Here, we first convert the percentage to a decimal by dividing by 100, then multiply by -2.

120/3 = 40.

Since 1.6 is greater than 40, the expression (-80%)(-2) is greater than 120/3, so the answer is >.

2. (-1750%70) = (-1750/100)(70) = -1225.

Since -1225 is less than -1008/48, the answer is <.

3. 240/(-80) = -3.

Since -3 is less than -150/50, the answer is <.

4. 675/(-45) = -15.

865/(-51) = -17.

Since -15 is greater than -17, the answer is >.

5. -3755%x = -15.

To find x, we need to isolate it by getting rid of the percentage.

Dividing both sides of the equation by -3755, we get x = -15 / -3755.

Simplifying, x = 0.004.

6. 22 = x%(-34).

To find x, we need to isolate it by getting rid of the percentage.

First, divide both sides of the equation by 22: x%(-34) / 22 = 1.

Then, multiply both sides by 22: x%(-34) = 22.

So, x = 22.

7. x%(-17) = -35.

To find x, we need to isolate it by getting rid of the percentage.

Dividing both sides of the equation by -17, we get x = -35 / -17.

Simplifying, x = 2.

8. -680 % x = 53.

To find x, we need to isolate it by getting rid of the percentage.

Dividing both sides of the equation by -680, we get x = 53 / -680.

Simplifying, x ≈ -0.078.
