Answer:
First one is 5 windows
Second one is 15 windows
Step-by-step explanation:
because 3 penguins are occupying 3 windows you got to subtract
18-5 = 15
15 is the number of windows avalible
so now you have to divide
15÷3= 5
which is ur answer for the first problem
then 15 for every one penguin so 15
