Question

The zoo has 218 animals in the outdoor exhibits and 454 animals in the indoor exhibits.estimate the number of animals the zoo has by rounding each number to the nearest hundred

Answer 1

Answer:

700 animals.

Step-by-step explanation:

We have been given that a zoo has 218 animals in the outdoor exhibits and 454 animals in the indoor exhibits.

Let us round both numbers to the nearest hundred.

Upon looking to tens value in our number we can see that it is less than 5, so we will round our number down.

We can also see that 218 in closer to 200 than 300. Rounding 218 to nearest hundred we will get 200, therefore, there are 200 animals in the outdoor exhibits.                    

Now let us round 454 to nearest hundred.

Upon looking to tens value in our number we can see that it is 5, so we will round our number up.  

We can also see that 454 is closer to 500 than 400. Upon rounding 454 to nearest hundred we will get 500, therefore, there are 500 animals in the indoor exhibit.

To find the total number of animals at zoo we will add 200 and 500.

$\text{t\Total number of animals at zoo}=200+500=700$

Therefore, there are 700 animals at the zoo.
