Question

Look at Andrea’s running journal.

A 2-column table with 3 rows titled Total distance Andrea Ran (kilometers). Column 1 has entries Monday, Tuesday, Wednesday. Column 2 has entries 3.6, 4.705, 5.92.

Explain how to add the three distances.

Answer 1

To add the three distances that Andrea ran, you'll want to follow these steps:

1. **Write down the distances**: You have three distances in kilometers:
- Monday: 3.6 km
- Tuesday: 4.705 km
- Wednesday: 5.92 km

2. **Align the numbers**: To make it easier to add them, align them by their decimal points:

```
3.600
+ 4.705
+ 5.920
```

3. **Add in columns**: Start adding from the rightmost side (the thousandths place) to the leftmost side (the whole numbers):
- **Thousandths**: 0 + 5 + 0 = 5
- **Hundredths**: 0 + 0 + 2 = 2
- **Tenths**: 6 + 7 + 9 = 22 (write down 2 and carry over 2 to the next column)
- **Units**: 3 + 4 + 5 + 2 (the carry over) = 14

4. **Write the sum**: Once you've completed the addition, combine the results. The total is:
- 14.225 km

Therefore, the total distance Andrea ran over the three days is **14.225 kilometers**.
