A ratio from boys to girls is 2:3. if there are 35 students how many are girls?
If the ratio is 2 boys : 3 girls,
then the ratio is 3 girls : 5 total
Set up a proportion:
3 girls / 5 total = x girls/ 35 total
5x = 105 {cross-multiplied}
x = 21 girls {divided both sides by 5}
If there are 35 students, there are 21 girls.
