Salutations!

<span>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'.

</span>5x + 4x = 180
<span>
Add 5 and 4

</span>9x = 180
<span>
</span>x = 20
<span>
Now, multiply the ratios by 20.

Boys = 20 </span>× 5 = 100

Girls = 20 × 4 = 80.

There were 80 girls.

Hope I helped (:

Have a great day!
