Question

Mario and Polly shared a whole pizza. They shared it in a ratio of 11:9. What percentage of the pizza did Mario have?

Answer 1

Mario had 55% of the pizza when he shared it with Polly in the ratio of 11:9.

Step-by-step explanation:

The student's question involves calculating what percentage of a pizza Mario had when he shared it with Polly in the ratio of 11:9. To solve this problem, first add the parts of the ratio together to determine the total number of parts the pizza was divided into, which is 11 + 9 = 20 parts. Mario's share is 11 parts out of this total. To find out what percentage of the pizza Mario had, divide the number of parts Mario had by the total number of parts and then multiply by 100 to get the percentage:

1. Calculate Mario's percentage: (11 / 20) * 100
2. Mario's percentage of the pizza: (0.55) * 100
3. Mario's percentage of the pizza: 55%

Therefore, Mario had 55% of the pizza.
