Explanation:

Step1: Convert percentage to decimal

To find the number of empty seats, we first convert the percentage \(40\%\) to a decimal. We know that \(40\%=\frac{40}{100} = 0.4\).

Step2: Calculate the number of empty seats

We multiply the total number of seats by the decimal form of the percentage. Let \(n\) be the number of empty seats. Given the total number of seats \(N = 70\), then \(n=N\times0.4\). Substituting \(N = 70\) into the formula, we get \(n=70\times0.4\).
