Yesterday 12 students brought their lunches from home. 7 of the students had peanut butter sandwiches and 5 of the students had 5 apples. Did 7+5=12 students have peanut butter sandwiches or apples in their lunches? Why or Why not?
Is it possible that some who brought sandwiches also brought apples?
To determine whether the total number of students who had peanut butter sandwiches or apples in their lunches is equal to 12, we simply need to add the number of students who had peanut butter sandwiches (7) to the number of students who had apples (5).
Mathematically speaking, 7 + 5 = 12.
So, the sum of 7 students with peanut butter sandwiches and 5 students with apples is indeed equal to 12. Therefore, 12 students in total had either peanut butter sandwiches or apples in their lunches.
