1. The problem is to verify the calculation of the ratio $180:(0.022 \times 2)$ and $180:(0.022 \times 1.1)$ and check if it equals 7438.01. 2. The formula used is division and multiplication: $$\text{Ratio} = \frac{180}{0.022 \times n}$$ where $n$ is the multiplier. 3. Calculate the first ratio: $$180 \div (0.022 \times 2) = 180 \div 0.044 = 4090.91$$ 4. Calculate the second ratio: $$180 \div (0.022 \times 1.1) = 180 \div 0.0242 = 7438.02$$ 5. The second calculation matches the given value 7438.01 approximately (rounded). 6. Therefore, the correct ratio for $n=1.1$ is approximately 7438.01, confirming the calculation.
