Answer 2

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

Let x be the number of people do not have a briefcase

By definition of proportion :

$\frac{3}{11} = \frac{x}{700}$

Multiply 700 both sides, we have

$\frac{3}{11} \times 700 = x$

Simplify:

x = 190.90≈ 191

Therefore, 191 people do not have a briefcase
