Simplify `(-30)/(5)-(18-9)/(-3)`

Answer

To simplify the expression \((-30)/(5) - (18 - 9)/(-3)\), we will follow these steps:

### Step 1: Simplify the first term
Calculate \(-30 / 5\).

\[ -30 / 5 = -6 \]

**Hint:** When dividing a negative number by a positive number, the result is negative.

### Step 2: Simplify the second term
First, simplify the expression inside the parentheses: \(18 - 9\).

\[ 18 - 9 = 9 \]

Now, substitute this back into the second term:

\[ (18 - 9) / (-3) = 9 / (-3) \]

Now calculate \(9 / (-3)\):

\[ 9 / (-3) = -3 \]

**Hint:** When dividing a positive number by a negative number, the result is negative.

### Step 3: Combine the results
Now we have:

\[ -6 - (-3) \]

This can be rewritten as:

\[ -6 + 3 \]

**Hint:** Subtracting a negative number is the same as adding its positive counterpart.

### Step 4: Perform the final calculation
Now, calculate \(-6 + 3\):

\[ -6 + 3 = -3 \]

### Final Answer
The simplified form of the expression is:

\[ \boxed{-3} \]
