`{:("Quantity A","Quantity B"),(10^(-3)xx((0.002)/(10^(-3))),0.02):}`

Answer

To solve the given question, we will evaluate both quantities step by step.

### Step 1: Analyze Quantity A
Quantity A is given as:
\[ \text{Quantity A} = 10^{-3} \times \left(\frac{0.002}{10^{-3}}\right) \]

### Step 2: Simplify the Expression
We can simplify the expression inside the parentheses:
\[ \frac{0.002}{10^{-3}} = 0.002 \times 10^{3} \]
This is because dividing by \(10^{-3}\) is equivalent to multiplying by \(10^{3}\).

### Step 3: Calculate \(0.002 \times 10^{3}\)
Now, we calculate:
\[ 0.002 \times 10^{3} = 0.002 \times 1000 = 2 \]

### Step 4: Substitute Back into Quantity A
Now, substituting back into Quantity A:
\[ \text{Quantity A} = 10^{-3} \times 2 \]

### Step 5: Calculate Quantity A
Calculating \(10^{-3} \times 2\):
\[ \text{Quantity A} = 2 \times 10^{-3} = 0.002 \]

### Step 6: Compare with Quantity B
Now we compare Quantity A with Quantity B:
- Quantity A = 0.002
- Quantity B = 0.02

### Step 7: Determine the Greater Quantity
Since \(0.02\) is greater than \(0.002\):
\[ \text{Quantity B} > \text{Quantity A} \]

### Final Conclusion
Thus, the answer is:
\[ \text{Quantity B is greater than Quantity A.} \]
