Question

There are 20 girls and 15 boys in a class a what is the ratio of number of girls to the number of boys be what is the ratio of number of girls to the total number of students in the class for exercise 12.1 in mathematics

Answer 1

Answer:

Step-by-step explanation:

Ratio of girls to boys = 20 / 15

                                   = 4 / 3

                                   = 4 : 3

Ratio of girls to total students = 20 / 35

                                                  = 4 / 7

                                                  = 4 : 7

Answer 2

Solution :-

Number of girls = 20

Number of boys = 15

In fraction = ${\bf{\frac{20}{15}}}$

In short form of the fraction = $\cancel{ \dfrac{20}{15} }$

Shortest form of fraction = $\large\frac{4}{3}$

In ratio = $\huge\pink{\mathfrak{\fbox{4:3}}}$
