`40%` of ? `= 240`

Options

A. `60`
B. `600`
C. `6000`
D. `960`

Answer

To solve the equation \( 40\% \) of \( ? = 240 \), we can follow these steps:

### Step 1: Understand the equation
We need to find a number (let's call it \( x \)) such that \( 40\% \) of \( x \) equals \( 240 \). This can be expressed mathematically as:
\[ 0.40 \times x = 240 \]

### Step 2: Isolate \( x \)
To find \( x \), we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by \( 0.40 \):
\[ x = \frac{240}{0.40} \]

### Step 3: Simplify the division
Now, we can simplify the division:
\[ x = \frac{240}{0.40} = \frac{2400}{4} \quad \text{(since } 0.40 = \frac{4}{10} \text{ and multiplying numerator and denominator by 10)} \]

### Step 4: Perform the calculation
Now, we calculate \( \frac{2400}{4} \):
\[ x = 600 \]

### Conclusion
Thus, the value of \( x \) is \( 600 \). Therefore, \( 40\% \) of \( 600 \) equals \( 240 \).

### Final Answer
The answer is \( 600 \).
