Explanation:

Answer 2

Answer:

(a) Number of girls = 20

Number of boys = 15

Ratio = $\frac{No. of girls}{No. of boys}$

         = $\frac{20}{15}$

         = $\frac{4}{3}$

∴ Required ratio is 4 : 3

(b) Total number of students = Number of girls + Number of boys

                                                = 20 + 15

                                                = 35

∴ Ratio = $\frac{Number of girls}{Total no. of students}$

            = $\frac{20}{35}$

            = $\frac{4}{7}$

∴ Required ratio is 4 : 7
