Estimate each of the following products by rounding off each number to the nearest ten :
`28xx63`

Answer

To estimate the product of 28 and 63 by rounding each number to the nearest ten, we can follow these steps:

### Step 1: Round 28 to the nearest ten
- The number 28 is a two-digit number.
- Look at the digit in the ones place, which is 8.
- Since 8 is greater than 5, we round up.
- We add 1 to the tens place (2) and change the ones place (8) to 0.
- Therefore, 28 rounded to the nearest ten is **30**.

### Step 2: Round 63 to the nearest ten
- The number 63 is also a two-digit number.
- Look at the digit in the ones place, which is 3.
- Since 3 is less than 5, we round down.
- We keep the tens place (6) the same and change the ones place (3) to 0.
- Therefore, 63 rounded to the nearest ten is **60**.

### Step 3: Calculate the estimated product
- Now we multiply the rounded numbers: 30 and 60.
- 30 × 60 = 1800.

### Final Answer
The estimated product of 28 and 63 is **1800**.
