Of the 30 girls who tried out for lacrosse team 12 were selected. Of the 40 boys that tried out 16 were selected. Are the ratios
satela [25.4K]
Girls;

Total number of girls who tried out = 30

Number of girls who got selected = 12

Ratio of girls on team to girls who tried out = \frac{12}{30} =  \frac{2}{5} = 2 : 5

Boys;

Total number of boys who tried out = 40

Number of boys who got selected = 16

Ratio of boys on team to boys who tried out = \frac{16}{40} =  \frac{2}{5} = 2 : 5

Hence, the ratios are the same.
