Answer:
25% of the students are girls.
Step-by-step explanation:
Key skills needed: Ratios, Percents, Fractions
1) There are 6 girls and 18 boys in the class --> This means that there are 6+18 or 24 people in the class total.
2) 6 of the 24 people are girls. So as a fraction --> 6/24 is the number of girls over the total number of people.
3) This can be simplified as 1/4 --> Divide 1 by 4 --> And this is 0.25
4) Multiply this by a 100 to get a percent form --> 25%
Hope you understood and have a nice day!! :D
