Final answer:
To find the ratio of pepperoni to sausage pizzas, subtract the number of sausage pizzas from the total number of pizzas Carson bought. Carson bought 7 pepperoni pizzas and 12 sausage pizzas, making the ratio 7:12.
Step-by-step explanation:
The student asked about the ratio of pepperoni to sausage pizzas that Carson bought. Carson bought a total of 19 pizzas, out of which 12 were sausage pizzas. In order to find the ratio of pepperoni to sausage pizzas, we need to subtract the number of sausage pizzas from the total number to find out how many were pepperoni.
So, the calculation is as follows:
- Total number of pizzas = 19
- Number of sausage pizzas = 12
- Number of pepperoni pizzas = Total - Sausage = 19 - 12 = 7
With 7 pepperoni pizzas and 12 sausage pizzas, the ratio of pepperoni to sausage pizzas is 7:12.
