Adenine always pairs with Guanine. So the percentage is the same.

Since adenine binds with thymine, T must be 18% as well, leaving 64% bewteen guanine and cytosine (which pair together), therefore you should have 32% guanine in that sample.

Since adenine pairs with thymine, thymine would have the same percentage. 18%*2=36%
The whole is 100%-36%=64% which is split between guanine and cytosine. Since they pair, they have the same percentage.
Therefore, 64%/2=32% guanine

This can be done only if you assume that the sample is double stranded DNA and not ssDNA (single stranded).
ONLY for double stranded DNA you can say,as the previous answers mention, that A pairs with T, thus T=A=18%, thus together they are 18*2=36%. The rest is G and C, thus G+C=100-36=64 %. But G and C form pairs so G=C and 2G=64 => G=32%

18% of A means 18% of T so 36% between A & T. so you are left with (100-36= 64%) of C and G. since C and G are equal, we split 64 in half and we are left with (64/2=32%) of G.
Answer is 32%.
