In the cafeteria 100 milk cartons were put out for breakfast at the end of breakfast 27 remained
I don't think so...
To find the number of milk cartons that were consumed during breakfast, you can subtract the number of remaining cartons from the initial number of cartons. In this case, the initial number of cartons was 100, and 27 remained.
To calculate the number of consumed cartons, you can use the subtraction operation.
100 - 27 = 73
Therefore, 73 cartons were consumed during breakfast in the cafeteria.
