Question

How do I round 3.047 to the nearest hundred and show the math

Answer 1

I believe you meant "hundredth" and not "hundreds"

Answer:

3.05

Step-by-step explanation:

To round a number to the nearest hundredth, we need to check the digit in the thousandth position:

1- If this digit was less than 5, we round down. This means that the number i the hundredth position is left as it is and all digits after it are converted to zeroes

2- If this digit was equal to or greater than 5, we round up. This means that we add one to the digit in the hundredth position and then convert all digits after it to zeroes

The given number is:

3.047

The digit in the thousandth position is 7 which is greater than 5.

Therefore, we round up

This means that our number would be:

3.050

The last zero is meaningless and can be discarded leaving us with 3.05 as an answer

Hope this helps :)

Answer 2

I'm guessing you mean 'hundredths', not 'hundreds', else that'll be 0.

First, find the hundredths spot.
The hundredths number is 4.

Look at the next number.
If it is more than 4, round it up.
If it is less than 5, round it down.

7 is more than 4, so we round up.

The final answer is 3.05.
