Answer 1

Answer:

Boys =18

Girls=36

Step-by-step explanation:

Let Total no of students be =x

No of girls =2/3×x

No of boys =1/3×x

x=54

No of boys is 1/3×54=18

No of girls is 2/3×54=36

Answer 2

Number of boys = 1/3

Means the number of girls = 2/3

___________ [ GIVEN ]

• We have to find the number of girls.

_____________________________

• Let total number of students be M.

» In a class the number of boys is 1/3 of the total number of students which is 54.

Number of boys = 1/3 M

Number of girls = 2/3 M

Also we have given total number of students = 54

A.T.Q.

→ $\dfrac{1}{3}$ × 54 = M

→ M = 18

Number of girls = $\dfrac{1}{3}$ × 54 = M

= 36

______________________________

Number of boys = 18

Number of girls = 36

________ [ ANSWER ]

______________________________

✡ Verification :

Total number of students = Number of boys + Number of girls.

54 = Number of boys + Number of girls.

From above calculations we have number of boys = 18 and number of girls = 36

=> 54 = 18 + 36

=> 54 = 54
