This is how you would set it up
42 47
----- -----
100 x
Then, cross multiply. You should get this:
42x = 4700
Then, solve that problem
42x = 4700
----- -------
42 42
x = 111 < (the answer turns out as a decimal but you should take the whole number)
Then subtract 111 and 100
111 - 100 = 11
Answer - 11%

You have to do what it says if you have to divide you divide if you have to multiply you multiply if you have to add you add and that is the same for subtraction as well.
I hope this helps you out.
Step-by-step explanation:
For the answer to the question above,
a1 = 40
<span>a2 = 20 </span>
<span>a3 = 10 </span>
<span>.. </span>
<span>aN = (1/2^N-1) a1 { in general aN= (r^N-1) A1 </span>
<span>a5 = (1/2^4) 40 = 40/16 = 2.5
</span>
So the answer to your question is 2.5
