Answer 1

To find the total number of meals served, we can first estimate the total by rounding:

- 64 lunches rounded to the nearest hundred is 100
- 273 dinners rounded to the nearest hundred is 300

Adding these estimated values:

100 + 300 = **400**

Now, let's add the actual numbers:

1. We list the numbers to add together:

```
273
+ 64
------
```

2. We start adding from the rightmost column:

- Units: 3 + 4 = 7
- Tens: 7 + 6 = 13 (write down 3 and carry over 1)
- Hundreds: 2 + 0 + 1 (the carried over 1) = 3

3. Putting it together, we have:

```
273
+ 64
------
337
```

So, the total number of meals served altogether is **337**.

Therefore:

- The fill in the blank answers are:
- 100 + 300 = **400**
- The total meals served is **337**.
