Answer:
9 cookies in 1 hour
Explanation:
45 cookies in 5 hours
We need to find how many cookies are baked in one hour
To convert 5 hours into 1 hour, we divide the 5 by 1
What we change on one side, we change on the other, so we need to divide the 45 by 5 as well
45 cookies in 5 hours
45÷5 cookies in 5÷5 hours
9 cookies in 1 hour
