Answer 2

Answer:

kindly see the answer below...

Step-by-step explanation:

Here, given that in a class total number of students is 45.

and the ratio of boys to girls is 3:2

now, let the number of boys be 3x and number of girls be 2x.

so,

$3x + 2x = 45$

$or \: \: 5x = 45$

$or \: \: x = 9$

therefore, total number of boys =3x=27 students

and, total number of girls =2x =18 students

then,

i) The no. of girls in the class is 18.

ii)The no. of boys in the class is 27.

III) The ratio of the total no. of boys to the total no. of students is

$\frac{27}{45}$

$= \frac{3}{5}$
