For the food described, find the percent of total calories from fat. Ranch dressing senving size of 2 tablespoons. \begin{tabular}{|l|c|} \hline \multicolumn{2}{|r|}{ Calories } \\ \hline Total & 70 \\ \hline From fat & 28 \\ \hline \end{tabular} The percent of total calories from fat is $\square \%$.

Step 1 ：Identify the total calories and the calories from fat. From the table, we see that the total calories are 70 and the calories from fat are 28.

Step 2 ：Divide the calories from fat by the total calories: \(\frac{28}{70} = 0.4\)

Step 3 ：Multiply the result by 100 to get the percentage: \(0.4 \times 100 = 40\%\)

Step 4 ：\(\boxed{40\%}\) is the percent of total calories from fat.
