Sure! Let’s solve each problem step by step. The task is to
determine the place and value of each underlined digit in the given decimal numbers.
We’ll use the
place value chart for decimals:
```
... | Hundreds | Tens | Ones | . | Tenths | Hundredths | ...
```
Each digit’s
place tells us its position (like “tens”, “hundredths”), and its
value is the digit multiplied by the place value (e.g., 3 in the tens place = 3 × 10 = 30).
