Answer:
Jada can bake 216 cookies in 6 hours.
Explanation:
We need to know how many she can cook in 6 hours.
She currently bakes 12 every 20 minutes
we know that 1 hour is 60 minutes.
So we multiply 12 by 3 to get 36 because we know 60 minutes divided by 20 minutes is 3 minutes.
Now we know that she bakes 36 cookies in 1 hour
But it asked for 6 hours so simple multiplication:
36 cookies per 1 hour X 6 hours
36X6= 216
