Here comes the procedure to estimate the numbers to the nearest thousands by rounding off.
Step 1: Find the digits in the thousands 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 thousands place to zeros.
Consider the number \(73280\).
Let us follow the steps to find the estimated number.
Step | Applying it | 73280 to thousands |
| 1 | Find the digits to the thousands place | 7\(3\)280 |
| 2 | Determine the digit to its right. | 7\(3\)280 |
| 3 | If this digit is \(5\) or greater add \(1\) to it. If it is lesser, then leave it as it is. | 7\(3\)280 (2<5). Leave it as it is. |
| 4 | Make the digits to the right of hundreds place \(5\) to zeros. | 73000 |
Thus, estimating the number \(73280\) to the nearest hundreds is \(73000\).
Now try to round the number 55171 to the nearest hundreds and tens place.
Estimation of 55171 to the nearest hundreds is 55200.
Estimation of 55171 to the nearest tens is 55170.
