Number of girls taking the ballroom dance lession = 2

Number of boys taking the ballroom dance lession = 7

ratio that compares the number of girls taking ballroom dancing lessons to the total number of students taking ballroom dancing lessons is :


\text{Ratio = Number of girls taking ballroom dance lesson : Number of boys taking ballroom dance lesson}


\begin{gathered} \text{Ratio = }\frac{Number\text{ of girls taking ballroom dancing lesson}}{Number\text{ of boys taking ballroom dancing lesson}} \\ \text{ Ratio=}(2)/(7) \\ \text{ ratio= 2:7} \end{gathered}
