Explanation:

Step1: Calculate total for thin - crust row

The total number of thin - crust slices sold is $32 + 44=76$.

Step2: Calculate relative frequency of thin - crust cheese

The relative frequency of thin - crust cheese slices is $\frac{32}{76}\times100\%\approx42\%$.

Step3: Calculate relative frequency of thin - crust one - topping

The relative frequency of thin - crust one - topping slices is $\frac{44}{76}\times100\%\approx58\%$.

Step4: Calculate total for thick - crust row

The total number of thick - crust slices sold is $17 + 11 = 28$.

Step5: Calculate relative frequency of thick - crust cheese

The relative frequency of thick - crust cheese slices is $\frac{17}{28}\times100\%\approx61\%$.

Step6: Calculate relative frequency of thick - crust one - topping

The relative frequency of thick - crust one - topping slices is $\frac{11}{28}\times100\%\approx39\%$.

Answer:
