3. Estimate to the nearest hundreds by rounding off

Here comes the procedure to estimate the numbers to the nearest hundreds by rounding off.

Step 1: Find the digits in the hundreds place.

Step 2: Determine the digit to its right.

Step 3: If this digit is \(5\) or greater, add \(1\) to it. If it is lesser, then leave it as it is.

Step 4: Make the digits to the right of hundreds place to zeros.

Consider the number \(1465\).

Let us follow the steps to find the estimated number.

Step	Applying it	1465 to hundreds
1	Find the digits to the hundreds place	1\(4\)65
2	Determine the digit to its right.	1\(4\)65
3	If this digit is \(5\) or greater add \(1\) to it. If it is lesser, then leave it as it is.	1\(4\)65 (\(6>5\)). Add \(1\) to it.
4	Make the digits to the right of hundreds place \(5\) to zeros.	1500

Thus, estimating the number \(1465\) to the nearest hundreds is \(1500\).

Now try to round the number 3769 to the nearest hundreds and tens place.

Estimation of 3769 to the nearest hundreds is 3800.

Estimation of 3769 to the nearest tens is 3770.
