Answer:
n = 1/8
Explanation:
We're told that 7/16 of the blood donations Lola connected are Type O, 3/8 are type A, 1/16 are type AB and the remaining are type B.
Let n represent the type B blood donations.
So we can go ahead and find n by adding all the fractions and equating it to 1;
[tex]\frac{7}{16}+\frac{3}{8}+\frac{1}{16}+n=1[/tex]
To clear the fractions, let's multiply both sides of the equation by the LCM which is 16, we'll have;
[tex]\begin{gathered} 7+6+1+16n=16 \\ 14+16n=16 \\ 16n=16-14 \\ n=\frac{2}{16} \\ \therefore n=\frac{1}{8} \end{gathered}[/tex]
Therefore, type B blood donations are 1/8
