Options

A. 1
B. `(1)/(2)`
C. `(1)/(10)`
D. 10

Answer

To solve the expression \((3.25 \times 3.20 - 3.20 \times 3.05) / 0.064\), we will follow these steps:

### Step 1: Calculate \(3.25 \times 3.20\)
\[ 3.25 \times 3.20 = 10.4 \]

### Step 2: Calculate \(3.20 \times 3.05\)
\[ 3.20 \times 3.05 = 9.76 \]

### Step 3: Substitute the results into the expression
Now we substitute the results from Step 1 and Step 2 into the expression:
\[ (10.4 - 9.76) / 0.064 \]

### Step 4: Perform the subtraction
\[ 10.4 - 9.76 = 0.64 \]

### Step 5: Substitute the result back into the expression
Now we have:
\[ 0.64 / 0.064 \]

### Step 6: Perform the division
\[ 0.64 / 0.064 = 10 \]

### Final Answer
Thus, the value of the expression \((3.25 \times 3.20 - 3.20 \times 3.05) / 0.064\) is equal to \(10\).
