Step-by-step explanation:
b/g=3/4 so if there are 12 boys this becomes
12/g=3/4 multiply both sides by g
12=3g/4 multiply both sides by 4
48=3g divide each side by 3
16=g
So there are 16 girls in the class.
Answer:
16
Step-by-step explanation:
Boys is written first so 3:4 the 3 stands for boy.
12 boys in class means that the 3 from 3:4 was multiplied 4 times so you do the same to other side. 4 times 4 is 16, therefore the answer is 16.

Answer:
f = 8
Step-by-step explanation:
- Apply the distributed property, so it now looks like this: 2f - 10 = 6
- Add 10 to each side, so it now looks like this: 2f = 16
- Divide each side by 2 to cancel out the 2 next to f. It should now look like this: f = 8
