A survey of patients at a hospital classified the patients by gender and blood type, as seen in the two-way table. Blood Type Male Female TOTAL A 105 93 198 B 99 84 183 O 160 140 300 AB 15 18 33 TOTAL 379 335 714 Refer to the table above. What percent of patients with type-B blood are male? 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.

To know the percent of male patients with type b blood, all you have to do is divide the number of male patients with B-blood type by the total number of patients with B-blood type. Then you multiply the quotient by 100 to get the percent as follows:
number of males with B-blood type = 99 males
total number of patients with B-blood type = 183 patients

% of males with B-blood type = (99/183) * 100 = 54.1%
