Question

the ratio of boys and girls in the class is 2 ratio 3 set up an equation between the boys and total number of students in class and then find the number of boys in a class of 25 students​

Answer 1

Answer:

i) 2:5

ii) 10

Step-by-step explanation:

ratio of boys to girls = 2:3

let no. of boys= 2x

and girls=3x

total no. of students= 2x+3x=5x

then

ratio of boys to total students =2x:5x =2:5

again

total no. of students = 25

or, 5x = 25

or, x=25/5

or, x=5

then

no. of boys = 2x = 2*5 = 10 ANS
