Mark should have rounded 271 to 300 and rounded 582 to 600: 300 + 500 = 900

Step-by-step explanation:

Rounding to the nearest hundred means rounding 271 to 300 and 550 to 600.

Think of it as

271 changes to 0.271

The 7 would be in the hundredths place.

7 is greater than 5; therefore, round up.

Now you have 0.3, change this back to it's normal decimal places to get 300.

550 changes to 0.550

Where the second 5 would be in the hundredths place.

5 is equal to 5; therefore, round up.

Now you have 0.6, change this back to it's normal decimal places to get 600.

Mark rounded to the nearest place which is not the same.
