    The answer for the last word problem is 32 cookies for 4 trays because 16 cookies x 2 = 32 cookies.

    Here is your word problem:
    In cooking class, Grade 8's were supposed to bake 24 cookies per 3 trays. If they got a total of 9 trays instead of 3, how many cookies did they make?

      The answer to your question is 72 cookies/9 trays I got this by dividing the number of trays(3) per 24 cookies which give me 8 as the answer. I times 8 by 9 (total of trays they got) and got 72.

      The answer to your question is $20/16L of milk. I got this by dividing 4L to $5 which give me $1.25 as the answer and I divided $20 to 1.25 and got 16.
      You can also get the answer 16 by dividimg 5 to 4x20 which is 80. 5/80 =16

    3,) Answer to your question:
    Krystal traveled 200 km / 4 hrs. If one hour is equal to 50 km, you just multiply 4 (hrs) by 50 km to get Krystal's speed per 4 hours.

    My question:
    Krystal decided to do a long drive from Winnipeg to Calgary and made a choice to not change her speed the whole drive. She will make it to Calgary in 6 hours. If her speed is 1036 km/hour . How many kilometers did she traveled the whole 6 hours?

      The answer to your question is 172.666666667km/hour. i divided 6 by 6216(1036x6) which give me the answer 1036 and i divide it again to 6 and it gives me the answer 172.66666667 km
