    simplify \(\dfrac{30}{3}\) and you get \(\dfrac{10}{1}\)

    alright so if you put each of the answers as a fraction and divide you will find your answer

    if you divide \(\dfrac{60}{4}\) by 4, you get \(\dfrac{15}{1}\)

    B is just like A just flipped so for A you got \(\dfrac{10}{1}\), for B it's just flipped = \(\dfrac{1}{10}\)
