Fill the following blanks with correct numbers :
`(-35)div…=-7`.

Answer

To solve the equation \((-35) \div \_\_ = -7\), we need to find the missing number that, when \(-35\) is divided by it, gives us \(-7\).

### Step-by-Step Solution:

1. **Set up the equation**:
We start with the equation:
\[ -35 \div x = -7 \]

2. **Rearrange the equation**:
To isolate \(x\), we can multiply both sides of the equation by \(x\):
\[ -35 = -7 \times x \]

3. **Divide both sides by -7**:
Now, we divide both sides by \(-7\) to solve for \(x\):
\[ x = \frac{-35}{-7} \]

4. **Simplify the right side**:
Since dividing two negative numbers results in a positive number, we simplify:
\[ x = \frac{35}{7} \]

5. **Calculate the division**:
Now we perform the division:
\[ x = 5 \]

6. **Final answer**:
Therefore, the missing number is:
\[ x = 5 \]

### Conclusion:
So, the complete equation is:
\[ (-35) \div 5 = -7 \]
