Answer: Lucy ate more pizzas because he ate more inches of pizza than Anthony.
Step-by-step explanation:
Anthony eats 2 slices of a large 18 inch pizza. Total number of slice in the 18 inch pizza is 8
The size of one slice in inches would be total length of pizza / number of slices. It becomes
18 / 8 = 2.25 inches
Anthony ate 2 ×2.25 = 4.5 inches of pizza.
Lucy eats 4 slices of a 12 inch pizza.
Total number of slice in the 12inch pizza is 8
The size of one slice in inches would be total length of pizza / number of slices. It becomes
12 / 8 = 1.5 inches
Lucy ate 4 × 1.5 = 6 inches of pizza.
Lucy ate more pizzas because he ate more inches of pizza than Anthony.
If there are 12 boys and 13 girls, there are 25 kids in the class total. This means that 13/25 are girls. In order to know the probability, you must divide 13 by 25, which gets an answer of 0.52, which is equal to 52%.
