John can bake 40 cookies in one hour. a school ordered 200 cookies. how many hours will john need to fill the order?

hello

John can bake 40 cookies in 1 hour and a school ordered 200 cookies, you need to find how many hours it is going to take to make those 200 cookies.

1 hour is 60 minutes

so              40 cookies in     60 minutes    (we will convert it to hours later )

                 200 cookies in    ????  minutes

step 1 : use fractions ->     (x being an unknown variable)

step 2: cross multiply until x is left alone on one side

step 3: solve for unknown and cross out like terms  : 200*60=1200, 1200/40=300

step 4 convert minutes to hours

          since 60 minutes are 1 hour

                    300 minutes are ? hours

step 4 cross multiply again  (300*1)/60 = 5 hours
