Arecent advertisement claimed that 2 out of every 5 doctors recommend a certain herbal supplement to increase energy levels. if a local hospital employs 90 doctors, how many doctors would you expect to recommend the supplement?

Using the principle of proportional relationship, the expected number of doctors which would recommend herbal supplement is 36

Setting up the relationship thus :

2 = 5 doctors

x = 90 doctors

Cross multiply

5x = 90 × 2

5x = 180

x = 180 / 5

x = 36

Therefore, we expect 36 doctors to recommend the supplement out of the 90 employed.
