Final answer:
To find out how much of the pizza is left, subtract the portions eaten by Hannah and Damian from the whole pizza. Hannah ate 1/4 of the pizza, leaving 3/4 of the pizza. Damian ate 2/3 of the pizza, leaving 5/12 of the pizza.
Step-by-step explanation:
To find out how much of the pizza is left, we can subtract the portions eaten by Hannah and Damian from the whole pizza.
Hannah ate 1/4 of the pizza, so we subtract 1/4 from 1 whole pizza. 1 - 1/4 = 3/4 of the pizza is left.
Damian ate 2/3 of the pizza, so we subtract 2/3 from the remaining 3/4. We can think of 3/4 as (2/4 + 1/4). Subtracting 2/3 from (2/4 + 1/4) is the same as subtracting 2/3 from 2/4 and 1/4 separately. (2/4 - 2/3) + 1/4 = 5/12.
Therefore, 5/12 of the pizza is left.
