Adding and Subtracting Decimals
6. 1 3/7
7. 3 15/16
8. 2 31/32
9. 7 1/3 spoonfuls
10. 4/15 pound

Answer 1

To add and subtract decimals, you first need to convert any mixed numbers or fractions into decimal form. Here's how to do it with the numbers you listed:

### Step 1: Convert Mixed Numbers and Fractions to Decimals

1. **1 3/7**:
- \( 3/7 \approx 0.4286 \) (rounded to four decimal places)
- \( 1 + 0.4286 = 1.4286 \)

2. **3 15/16**:
- \( 15/16 = 0.9375 \)
- \( 3 + 0.9375 = 3.9375 \)

3. **2 31/32**:
- \( 31/32 = 0.96875 \)
- \( 2 + 0.96875 = 2.96875 \)

4. **7 1/3 spoonfuls**:
- \( 1/3 \approx 0.3333 \) (rounded to four decimal places)
- \( 7 + 0.3333 = 7.3333 \)

5. **4/15 pound**:
- \( 4/15 \approx 0.2667 \) (rounded to four decimal places)

### Step 2: Summary of Converted Values

- \( 1 3/7 \approx 1.4286 \)
- \( 3 15/16 \approx 3.9375 \)
- \( 2 31/32 \approx 2.96875 \)
- \( 7 1/3 \approx 7.3333 \)
- \( 4/15 \approx 0.2667 \)

### Note on Adding or Subtracting

If you want to add or subtract these decimals, align them by the decimal point and then perform the operation.

For example, if you wanted to add \( 1.4286 \) and \( 3.9375 \):

```
1.4286
+ 3.9375
---------
5.3661
```
