Question

The ratio of Boys to Girls ​

Answer 1

Answer:480

Step-by-step explanation:

Let the number of boys and girls be 4x and 5x

so

4x+5x=1080

9x = 1080

or x = 1080/9

so x = 120

then number of boys = 4x = 4*120 = 480

So the number of boys is 480

Answer 2

Step-by-step explanation:

Let , the ratio constant be x

therefore, boys = 4x

and girls = 5x

According to questions,

4x + 5x = 1080

=] 9x = 1080

=] X = 1080/ 9

=] X = 120

therefore, boys = 4x = 4 × 120

= 480

girls = 5x = 5 × 120

= 600
