    False. You have it exactly backwards.

    5x = 7y

    Divide both sides by 5:

    x = 7y/5

    Then divide both sides by 7:

    x/7 = y/5

    Answer:

    False, it should be x:7 = y:5

    5 x = 7 y

    x / y = 7 / 5

    False.

    5x = 7y

    x = 7y/5

    x/5 = 7y/25 = y/(25/7)

    x:5 = y:25/7
