    Step-by-step explanation:

    You could find 5/⅓

    by using 5 * 3

    Knowing that:

    i. Any number multiplied by 1, gives the number itself.

    ii. Dividing any number by itself gives 1.

    You would agree with me that

    i. (5*3) / (5*3) = 1

    ii. Writing 5/⅓ as 5/⅓ * 1 doesn't change the value.

    Then I can write 5/⅓ as

    5/⅓ * (5*3) / (5*3) = 1

    This can become

    [5 * (5*3) ] / [ (⅓) * (5*3) ]

    = 75 / (15/3)

    = 75/5

    = 15

    In a similar way,

    12 / 3/5

    = [12 / (3/5) ] * [ (5*3) / (5*3) ]

    = 12 * (5*3) / (3/5) * (5*3)

    = (12*5*3) / [ (3*5*3) / 5]

    = 180 / (45/5)

    = 180 / 9

    = 20
