Answer 1

Step-by-step explanation:

let girl be 3x and boy be 2x

according to questions

3x+2x =80

5x =80

x=80÷5

x= 16

3x=3×16=48

Answer 2

Answer:

There are 48 girls.

Step-by-step explanation:

Step 1 of 3

Given: The total number of students are 80.

The ratio of the boys to the girls is 2:3.

Let the common ratio be $x$.

Then,

The number of the boys = $2x$

The number of the girls = $3x$

Step 2 of 3

The number of the boys + the number of the girls = the total no. of students

⇒ $2x+3x=80$

Solve the equation for $x$ as follows:

⇒ $5x=80$

⇒ $x=16$

Step 3 of 3

Thus, the number of the girls = 3 × 16

                                                  = 48 girls

Final answer: There are 48 girls out of 80.
