Answer:
Step-by-step explanation:
The ratio of boys to girls is 12 to 16, 12:16 or 12/16 (all different ways this can be written). The fraction form 12/16 can be reduced by dividing by the greatest common factor. Both 12 and 16 are divisible by 4, so the reduced fraction is 12/4 over 16/4 = 3/4. In other words, there are 3 boys for every 4 girls in the class.
If you knew that 8*300=2400
Then you could likely figure that 8*20=160
And then just add the two together to get 2560
