Answer:
To estimate how many cupcakes each classroom in Armond's grade can have, we need to multiply the number of trays of cupcakes by the number of cupcakes in each tray, and then divide that total by the number of classrooms.
First, we multiply 7 trays by 12 cupcakes per tray. This gives us a total of 84 cupcakes.
Next, we divide 84 cupcakes by the number of classrooms, which is 5.
When we divide 84 cupcakes by 5 classrooms, we find that each classroom can have approximately 16.8 cupcakes.
Since we can't have a fraction of a cupcake, we need to round our answer.
Rounding down, each classroom can have approximately 16 cupcakes.
Therefore, if the cupcakes are shared equally, each classroom in Armond's grade can have around 16 cupcakes.
