If 2 dots are equal to 3 dashes and 5 dashes equal to 7 stars, what is the ratio of one dot to one star?

OpenStudy (anonymous):

since 2 dots equla to 3 dashes hence 10 dots equal to 15 dashes --> 1 now 5 dashes equal to 7 star 15 dashes equal 21 star---> 2 combining 1 and 2 we wcan say 10 dots equal to 21 star and so on ...hence 1 dot : 1star = 21 : 10
