Question

Subway I 8 out of 11 people are carrying a briefcase based on this information if there are 700 people on a subway then about how many do not have a briefcase

Answer 1

Answer: There are approximately 191 people that do not have a briefcase.

Explanation:

Since we have given that

8 out of 11 people are carrying a briefcase.

Then fraction of people carrying a briefcase =
`(8)/(11)`

Fraction of people do not have a briefcase =
`1-(8)/(11)=(11-8)/(11)=(3)/(11)`

Similarly, if there are 700 people on a subway, then we will find the number of people do not having a briefcase.

Since there is a direct variation,

`(3)/(11)=(x)/(700)\\\\\\x=(700* 3)/(11)\\\\\\x=190.90\\\\\\x\approx 191`

Hence, there are approximately 191 people that do not have a briefcase.
