Answer 1

n = 1/8

Step-by-step 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;

`(7)/(16)+(3)/(8)+(1)/(16)+n=1`

To clear the fractions, let's multiply both sides of the equation by the LCM which is 16, we'll have;

`\begin{gathered} 7+6+1+16n=16 \\ 14+16n=16 \\ 16n=16-14 \\ n=(2)/(16) \\ \therefore n=(1)/(8) \end{gathered}`

Therefore, type B blood donations are 1/8
