The ratio of boys to girls in a school is 5:4. if there are 180 students, how many girls are there?

Let the number of girls and boys be 'x'.

[tex]5x + 4x = 180[/tex]

Add 5 and 4

[tex]9x = 180 [/tex]

[tex]x = 20 [/tex]

Now, multiply the ratios by 20.

Boys = 20 × 5 = 100

Girls = 20 × 4 = 80.

There were 80 girls.

Hope I helped (:

Have a great day!
