Answer:

72 doctors recommended the medicine

Step-by-step explanation:

The question above is interpreted thus.

9 out of 10 implies 9/10. If 80 doctors were surveyed, the number of doctors that recommended the medicine is 9/10 of 80 doctors. Therefore,

$\frac{9}{10} \: of \: 80$

$= \frac{9}{10} \times 80$

$= \frac{9 \times 80}{10}$

$= \frac{720}{10}$

$= 72$

Therefore, in a survey where 9 out of 10 doctors recommended a certain medicine; and 80 doctors were surveyed, 72 doctors recommended the medicine.
