    Answer:

    191 people do not have a briefcase.

    Step-by-step explanation:

    Given:

    On a subway 8 out of 11 people are carrying a briefcase.

    If there are 700 people on the subway.

    Now, find the people do not have a briefcase.

    As given, 8 out of 11 are carrying a briefcase.

    So, if there are 700 people on the subway.

    Using the above information we need to get the number of people carrying briefcase.

    Let the number of people carrying briefcase be x.

    So, 8 is equivalent to 11.

    And, x is equivalent to 700.

    Now, to solve by using cross multiplication method:

    \frac{8}{11} =\frac{x}{700}

    By cross multiplying we get:

    5600=11x

    Dividing both sides by 11 we get:

    509.09=x

    Approximately, x=509.

    Thus, 509 out of 700 people are carrying briefcase.

    Now, to get the people not carrying briefcase we subtract 509 from 700:

    700-509

    =191.

    Therefore, 191 people do not have a briefcase.
