Estimate each of the following products by rounding off each number to the nearest ten :
`54xx47`

Answer

To estimate the product of 54 and 47 by rounding each number to the nearest ten, follow these steps:

### Step-by-Step Solution:

1. **Identify the numbers**: We have the numbers 54 and 47.

2. **Round 54 to the nearest ten**:
- Look at the digit in the ones place of 54, which is 4.
- Since 4 is less than 5, we do not increase the tens digit (5).
- Therefore, rounding 54 gives us 50.

3. **Round 47 to the nearest ten**:
- Look at the digit in the ones place of 47, which is 7.
- Since 7 is greater than 5, we increase the tens digit (4) by 1.
- Therefore, rounding 47 gives us 50.

4. **Multiply the rounded numbers**:
- Now we multiply the rounded values: 50 × 50.
- Calculate: 50 × 50 = 2500.

5. **Final estimated product**:
- The estimated product of 54 and 47 is 2500.

### Summary of Steps:
- Round 54 to 50.
- Round 47 to 50.
- Multiply the rounded numbers: 50 × 50 = 2500.
