The ratio of boys to girls in my class is 3:4. If there are 12 boys, how many girls are there in my class?

9 girls

Step-by-step explanation:

12/4=3 boys

Multiple 3x3 to get the 9 girls

16 girls

Step-by-step explanation:

Number of girls = x

3:4 = 12:x

= 3/4 = 12/x

cross multiply:

4 x 12 / 3 = 16

so there are 16 girls in the class.
