    Answer:

    123 if your going to the nearest whole number

    Step-by-step explanation:

    Since

    6 : 7 = X : 143

    Then we know

    6/7 = X/143

    Multiplying both sides by 143 cancels on the right

    143 × (6/7) = (X/143) × 143

    143 × (6/7) = X

    Then solving for X

    X = 143 × (6/7)

    X = 122.57142857143

    Therefore

    6 : 7 = 122.57142857143 : 143
