`12.5xx8.4xx7.6=?`

Options

A. 787
B. 788
C. 799
D. None of these

Explanation

To solve the expression \( 12.5 \times 8.4 \times 7.6 \), we will follow these steps:

### Step 1: Multiply the first two numbers
First, we will multiply \( 12.5 \) and \( 8.4 \).

\[ 12.5 \times 8.4 = 105 \]

### Step 2: Multiply the result by the third number
Next, we take the result from Step 1 and multiply it by \( 7.6 \).

\[ 105 \times 7.6 \]

To perform this multiplication, we can break it down:

\[ 105 \times 7.6 = 105 \times (7 + 0.6) = (105 \times 7) + (105 \times 0.6) \]

Calculating each part:

1. \( 105 \times 7 = 735 \)
2. \( 105 \times 0.6 = 63 \)

Now, we add these two results together:

\[ 735 + 63 = 798 \]

### Final Answer
Thus, the value of \( 12.5 \times 8.4 \times 7.6 \) is \( 798 \).
