This problem is easy.You just need to realize that the numbers $5*30=11$ first divide 30 by 5 and then add it to 5=11 Second one $6*36=12$ divide 36/6=6+6=12 so for $9*27=?$ you divide 27/9=3 and then add it to 9 equals 12

The operation $a\text{x}b$ is equivalent to the operation $a+\frac{b}{a}.$ Substituting $a=9$ and $b=27,$ $9+\frac{27}{9}=9+3=\boxed{12}$
