`? xx 48 = 173 xx 240`

Options

A. 545
B. 685
C. 865
D. 495

Answer

To solve the equation \( ? \times 48 = 173 \times 240 \), we will follow these steps:

### Step 1: Set up the equation
We start with the equation:
\[ ? \times 48 = 173 \times 240 \]

### Step 2: Isolate the question mark
To find the value of \( ? \), we need to isolate it on one side of the equation. We can do this by dividing both sides by 48:
\[ ? = \frac{173 \times 240}{48} \]

### Step 3: Simplify the right side
Now we will simplify the right side of the equation. First, we can simplify \( \frac{240}{48} \):
\[ \frac{240}{48} = 5 \]
So, we can rewrite the equation as:
\[ ? = 173 \times 5 \]

### Step 4: Calculate \( 173 \times 5 \)
Now we need to multiply \( 173 \) by \( 5 \):
\[ 173 \times 5 = 865 \]

### Final Answer
Thus, the value of \( ? \) is:
\[ ? = 865 \]
