    1.
    10:2 is not in lowest terms, both numbers divide by 2
    10:2
    = 5:1

    2.
    r/5= 9/21
    r = 45/21 = 15/7 which is appr 2.143
    They should have given 15/7 as the correct choice,
    the rounded off number is not exact.

    3. puzzled by your choice.

    it takes 3 cups to make 9 dozen
    so it takes 9 cups to make 9 dozen

    4.
    39/12 , this fraction does not reduce any more

    5. 62.6 gallons/10 months = 6.26 gallons/month
    (you had that one right, finally!)

    6. If 3 cookies cost $2.97 then
