Question 1082551
<pre>
Any time we have a:b:c, we can interpret that as:

The fraction of the total which a is, is {{{a/(a+b+c)}}}
The fraction of the total which b is, is {{{b/(a+b+c)}}}
The fraction of the total which c is, is {{{c/(a+b+c)}}}

-----------------

We have A:T:B = 1:3:4

So the fraction of the total which Andy gets is {{{1/(1+3+4)}}} or {{{1/8}}}.

So {{{1/8}}} is the FRACTION of the total which Andy gets.

All we have to do is change the fraction {{{1/8}}} to a percent.

Divide 1 by 8, get 0.125, move the decimal two places right
and put on a %

Answer 12.5%
