Since all the answers are ratios of integer values, lets multiply both sides of the ratio by 3 in order to get integers in both sides of the ratio. After this, we could multiply both sides again by an integer in order to link to one of the given answers.
2 : 1/3
2*3 : (1/3)*3
6:1
Since this ratio match with (A), we can directly select this option.
