    The total number of people in the room is 14

    Step-by-step explanation:

    The ratio of the number of women to the number of men to the number of children in a room is 5:2:7

    So, there are

    5 women 2 men 7 children

    (1) The total number of women and children in the room is 12.

    5 women and 7 children=12

    (2) There are fewer than 4 men in the room.

    There are 2 men, that's fewer than 4

    So, the total number of people is 5+2+7 = 14
