TOTAL 379 335 714
What percent of all patients are blood type AB? Round your answer to the nearest tenth of a percent. Type a numerical answer in the space provided. Do not include % or spaces in your answer.

Answer 1

To get the percentage of patients with AB blood type, divide the number of patients with AB blood type by the total number of patients and then multiply the quotient by 100 to get the percentage as follows:
Total number of patients with AB blood type = 33 patient
Total number of patients = 714 patient

% of patients with AB blood type = (33/714) * 100 = 4.6%
