To estimate the product of 56,875 and 88 by rounding each number to its greatest place, follow these steps:

### Step 1: Round 56,875 to the nearest 10,000
- The greatest place value in 56,875 is 10,000.
- Look at the last four digits: 6,875.
- Compare 6,875 to 5,000. Since 6,875 is greater than 5,000, we round up.
- Therefore, 56,875 rounds to **60,000**.

### Step 2: Round 88 to the nearest 10
- The greatest place value in 88 is 10.
- Look at the last digit: 8.

### Step 3: Multiply the rounded numbers
- Now, multiply the rounded values: 60,000 and 90.
- First, write down the zeros: 60,000 has 5 zeros.
- Multiply the digits: 6 (from 60,000) and 9 (from 90).
- 6 multiplied by 9 equals 54.
- Combine this with the zeros: 54 followed by 5 zeros gives us **5,400,000**.

### Final Answer
The estimated product of 56,875 and 88 is **5,400,000**.
