of students at a school are girls. If there are 2367 students at the school, how many are boys?

Answer 1

The number of boys in school is 1052

Solution:

Let "x" be the number of boys in school

There are 2367 students at the school

5/9 of students at a school are girls

Therefore,

To find: number of boys in school

Number of boys = total students - number of girls

Number of boys = 2367 - 1315

Number of boys = 1052

Thus, number of boys in school is 1052

Answer 2

Step-by-step explanation:

Alright, so let’s make the information given into equations

b= # of boys

g= # of girls

x= total number of students = b + g

4/9(b+g)=g which becomes 4/9b + 4/9g = g

4/9b = 5/9g

g= ((4/9)b)/(5/9)

g + 17 = b

Now solve for g

g= b-17

Now set those both equal to each toher

b-17 = (4/9b)/(5/9)

b-17= 0.8b

b-0.8b = 17

b(1–0.8) = 17

b(0.2) = 17

b= 17/0.2

b= 85

Now we know how many boys

Solve for girls

g = b-17

g=68

So there are 85 boys and 68 girls!
