By which number should 0.022 be multiplied so that product becomes 66 ?

Options

A. 3000
B. 3200
C. 4000
D. 3600

Answer

To find the number by which 0.022 should be multiplied so that the product becomes 66, we can follow these steps:

### Step 1: Set up the equation
Let the required number be \( x \). According to the problem, we have:
\[ 0.022 \times x = 66 \]

### 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 by 0.022:
\[ x = \frac{66}{0.022} \]

### Step 3: Simplify the division
To simplify \( \frac{66}{0.022} \), we can eliminate the decimal by multiplying the numerator and the denominator by 1000:
\[ x = \frac{66 \times 1000}{0.022 \times 1000} = \frac{66000}{22} \]

### Step 4: Perform the division
Now, we can perform the division:
\[ x = 3000 \]

### Conclusion
Thus, the number by which 0.022 should be multiplied to get 66 is:
\[ \boxed{3000} \]
