Question

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?

Answer 1

see the explanation

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
`5` (this is called rounding down)

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

In this problem we have

`5.63`

so

step 1

We want to keep the digit
`6`

step 2

The next digit is
`3` which is less than
`5`, so no change is needed to
`6`

therefore

The number rounded to the nearest tenth is 5.6
