kotykmax [81]

Answer:

17285 female doctors

Step-by-step explanation:

We need 31.2% of 55,400 doctors to do this we multiply 31.2% by 55,400

0.312 is 31.2% as a decimal

so we do...

0.312 * 55,400 = number of female doctors

if type that into a calculator you get 17284.8

17.284 rounds to 17285

so the answer is...

17285 female doctors
