Question

In class there are 45 students if thenumber of boys is two-third of the number of girls Find the number of girl ​

Answer 1

Answer:

Number of girls = 27

Step-by-step explanation:

Number of students in a class - 45

Number of girls - $x$

Number of boys - $\frac{2}{3} x$

∴ from the given data,

45 = $x + \frac{2}{3} x$

45 = $\frac{3x}{3} + \frac{2x}{3}$

45 × 3 = $5x$

135 = $5x$

$\frac{135}{5} = x$

27 = $x$

∴ There are 27 girls in the classroom
