Question

1 Lola collects blood donations at a clinic. 7/16 of the donations are of Type 0, 3/8 are of Type A, and 1/16 are Type AB. The remaining are Type B. What part of the blood donations are Type B?

Answer 1

n=1/8

Step-by-step explanation:

From the diagram, if we sum up all the parts, we have:

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

We solve the equation above for n.

The lowest common multiple of 16 and 8 = 16

Therefore:

`(7+6+1)/(16)+n=1`

Therefore:

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

The value of n is 1/8.
