Yes, an SRS by definition is a sample that is divided into groups that share an attribute and then those groups are combined. In this case the groups are divided by gender.

12:8 can also be written as $\boxed{ \frac{12}{8}}$ To find the percent you have to do 12÷8 and that equals 1.5, then you have to do 1.5×100 and that equals 150. The ratio, 12:8 as a percent is 150%
