Just randomly prepare a list of members of each household. Name them as you wish. Do this for 20 households. Then, count the total number of female and male according to your report.

Suppose let the no. of male and female be x and y
Therefore, ratio will be y/x
Convert it to the simplest fraction, and you will get your ratio say a:b
