Answer:
191 people do not have a briefcase
Step-by-step explanation:
Proportion states that the two ratios or fraction are equal
As per the given condition:
On the subway 8 out of 11 people are carrying a briefcase.
⇒Total number of people = 11
and number of people carrying a briefcase = 8
Remaining number of people that do not carrying a briefcase = 11-8 = 3
Now,
Based on this information, if there are 700 people on the subway
