    1. I think it is 10 because 6×5 is 30 and 10,3 times is 30.
    2.The answer is 5 because 5×4 is 20 and 5,4 times is 20.
    3. This answer is 12 because 12×5 is 60 and if you do 12,5 times it will equal 60. Also 6×10 is 60.

    I think the 1st answer is 10 because if you skip count 10, 3 times you’ll get 30 (10,20,30)
    I think the 2nd answer is 5 because if you skip count 5, 4 times you’ll get 20 (5,10,15,20)
    I think the 3rd answer is 12 because if you skip count 12,5 time you’ll get 60 and 6×10=60 (12,24,36,48,60).

    I think the answer is 10 because 6 x 5 is 30 so 10 x 3 is 30
    (10,20,30)
    I think the answer is 5 because 4 x 5 is 20
    (5,10,15,20)
    I think the answer is 12 because 12 x 5 is 60
    (12,24,36,48,60) 10 x 6 = 60.

    #2:I think the answer is 5 because 5×4 is 20.(5,10,15,20)
