    Answer:

    The rates form a proportion

    Step-by-step explanation:

    we know that

    If two rates form a proportion

    then

    The two rates must be equivalent

    so

    \frac{7}{9}=\frac{42}{54}

    Multiply in cross

    7(54)=9(42)

    378=378 —-> is true

    therefore

    The rates form a proportion
