Set up the ratio
2 12
- = -
3 x
2/3 represents the ratio, 12 represents the boys, x represents the girls.
Cross multiply and get 2x = 36
Divide both sides by 2 and get x=18
Therefore, there are 18 girls!
Hope this helps! Feel free to comment with any questions!! xoxo

Number of girls is 18.
Boy : Girl = 2:3
Boy = 12
Boy/Girl = 2/3
2 Girl = 3 Boy
2 Girl = 3 x 12 (Boy = 12)
Girl = 36/2
Girl = 18
Boy : Girl = 2:3
Boy = 12
Boy/Girl = 2/3
2 Girl = 3 Boy
2 Girl = 3 x 12 (Boy = 12)
Girl = 36/2
Girl = 18

If the ratio of boys to girls is 2:3 and the number of boys is 12, then the number of girls will be (12/2) × 3.

If the ratio is 2:3 that means that there are 3 girls for every 2 boys. If there are 12 boys then there must be (12/2) * 3 = 6*3 = 18 girls.

Let number of girls = x
→2 : 3:: 12:x
2/3=12/x→x=12x3/2=18
Number of girls = x =18
→2 : 3:: 12:x
2/3=12/x→x=12x3/2=18
Number of girls = x =18

2/3= 12/x
12/2=6
6 x 3= 18
12 boys, 18 girls
12/2=6
6 x 3= 18
12 boys, 18 girls

2/3= 12/x
12/2=6
6 x 3= 18
12 boys, 18 girls
12/2=6
6 x 3= 18

The ratio of boys to girls is 2 : 3
So .. there are 2 boys for every 3 girls.
There are 12 boys .. which is 2 x 6
So there are 18 girls .. .........3 x 6
