Estimating to the nearest hundreds by rounding off

Once Ayush went to market with his mother.

They bought one kg of both oranges and apples for

But his mother gave only to the shopkeeper and he didn’t disagree with that money.

Now, a question came in Ayush’s mind why the shopkeeper didn’t demand the actual cost.

He asked his mother about this, she replied that the value was a estimated value.

Till now Ayush was confused so, his mom started teaching him about the estimation to the nearest hundreds by rounding off.

Let’s discuss the estimation of numbers to the nearest hundreds by rounding off.

Let’s consider a group of numbers from to as,

Here we can observe that number to are closer to in comparison with .

And, the numbers to are closer to in comparison with .

In case of estimating to nearest hundred, we always look at the hundreds value which are nearest to the number.

We follow same concept for finding out estimated values nearest to hundreds.

Let us consider a digit number and we need to estimate this to the nearest hundreds.

Here, we observe that it is nearer to so, it is rounded off to .

Now, suppose we consider a digit number and we need to estimate this number to the nearest hundreds by rounding off.

We can clearly observe that is nearest to . So, its estimated value will be

We see some other examples and round off them to their closer number as

Revision

Number to are closer to in comparison with so, it is rounded off to .

Number to are closer to in comparison with so, it is rounded off to .

In case of estimating to nearest hundred we always look at the hundreds value which are nearest to the number.
