Answer 1

$\begin{gathered} \text{the type }B\text{ donations are all that are not type O, or A or AB, so it is } \\ 1-\frac{7}{16}-\frac{3}{8}-\frac{1}{16}=\frac{16}{16}-\frac{7}{16}-\frac{6}{16}-\frac{1}{16} \\ =\frac{16-7-6-1}{16} \\ =\frac{2}{16} \\ =\frac{1}{8} \\ \\ So\text{ 1/8 part of the blood donations are Type B} \end{gathered}$
