Final Answer:
There were 7 classes given pies, as each class got 1 1/2 pies and 10 1/2 pies were distributed in total.
Step-by-step explanation:
The question requires us to calculate how many classes were given pies during the year-end party. We can solve this problem by breaking it down into smaller steps. Firstly, we need to know how many pies were distributed in total. The question states that there were 10 1/2 pies. We can represent this as 10⅜ pies. Secondly, we need to know how many pies each class was given. The question states that each class was given 1 1/2 pies. This can be represented as 1⅝ pies.
Thirdly, we need to find the total number of classes which were given pies. We can do this by dividing the total number of pies by the number of pies given to each class. Therefore, if we divide 10⅜ pies by 1⅝ pies, we get the total number of classes, which is 7. Therefore, 7 classes were given pies during the year-end party.
In conclusion, the total number of classes which were given pies during the year-end party was 7. This was calculated by dividing the total number of pies (10⅜) by the number of pies given to each class (1⅝).
