Ian mailed a package that weighed 5.63 pounds. what is the first step in rounding this number to the nearest tenth? what is the next step? what is 5.63 rounded to the nearest tenth?

see the explanation

Step-by-step explanation:

we know that

To Round a number

step 1

Decide which is the last digit to keep  

step 2

Leave it the same if the next digit is less than (this is called rounding down)  

But increase it by   if the next digit is   or more (this is called rounding up)

In this problem we have

so

step 1

We want to keep the digit

step 2

The next digit is which is less than , so no change is needed to

therefore

The number rounded to the nearest tenth is 5.6

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
