Salutations!
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!
