- The initial number of stamps: Janet starts with 36 stamps
- Grouping the stamps: Janet divides 36 stamps into 9 equal groups------> To find out how many stamps are in each group, we must divide the initial number of stamps by the number of groups:
36 divided by 9 equals 4 stamps per group
- Janet adds 2 more stamps to each group. Since there were 9 stamps in each group originally we must calculate the new total number of stamps:
Stamps added x Number of Groups---> 2x9= 18
The new total of stamps= Orignal Number of Stamps + Stamps added--> 36+18= 54
- Janet gave 4 stamps to each of her 13 friends.
Total number of stamps given away= Number of Friends x Stamps per friend---> 13x4= 52
- How many stamps are remaining?
Remaining Stamps= Total Number of New Stamps - Total Number of Stamps Given away ----> 54-52= 2
- The final answer shows that Janet has 2 stamps remaining.
