Find the ratio of number of regular sized Pizzas baked on Thursday and Friday together to the sum of number of large and medium sized Pizzas baked on Friday.
For Thursday: Total number of Pizzas baked = 160 Sum of the large and medium sized Pizzas baked = 110 So, number of regular sized Pizzas baked = 160 – 110 = 50 Number of regular sized Pizzas baked - Number of large sized cakes baked = 40 Number of large sized Pizzas baked = 50 – 40 = 10 Number of medium sized Pizzas baked = 110 – 10 = 100 Similarly, we can find the required data for the other days too. Required ratio = (50+70) : (50+70) = 120:120 = 1:1
