Question

For every person who actually has the flu, there are 6 people who have flu-like symptoms resulting from a cold. If a doctor sees 40 patients, write and solve a proportion to determine how many of these you would expect to have a cold

Answer 1

Answer: The number of people can be expected to have cold = 34

Explanation:

Given: The ratio of people who actually have the flu to the people who have flu-like symptoms is 1:6.

If a doctor sees 40 patients, then the number of people can be expected to have cold =
`40*(6)/(1+6)`

`=40*\frac6{7}`

`=(240)/(7)\\\\=34.29\approx34`

Hence, the number of people can be expected to have cold = 34
