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.
