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.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
