Final answer:
To find out how much pizza is left, subtract the amounts Dane and Ayesha ate from the original whole pizza. There is 2/5 of the pizza left.
Step-by-step explanation:
To find out how much pizza is left, we need to subtract the amounts Dane and Ayesha ate from the original whole pizza. Dane ate 2/5 of the pizza, which is equal to 2 slices out of 5. Ayesha ate 2/10 of the pizza, which is equal to 2 slices out of 10.
To find the combined amount they ate, we need to find a common denominator. The common denominator for 5 and 10 is 10. So, Dane ate 4/10 and Ayesha ate 2/10.
To find the amount of pizza left, we subtract the combined amount they ate from the whole pizza. Whole pizza - Combined amount eaten: 1 - (4/10 + 2/10) = 1 - 6/10 = 4/10 or 2/5. So, there is 2/5 of the pizza left.
