The ratio of boys to girls in a venior Senior Promede is 4:3 Jane counted that- there are 12 more boys than girls. How many boys and girls, how many are there
in the prom?​

Answers

Answer:

36 girls, 48 boys . Total of 84 in the prom.

Step-by-step explanation:

Let the number of girls be x, then the number of boys is x+12.

So we have the equation:

4/3 = (x + 12) / x

4x = 3x + 36

x = 36.

So there are 36 girls and 48 boys in the prom.

A count went from 605 to 203. What was the approximate percent decrease? Round the numbers to find an estimate of the percent decrease. The percent decrease was approximately 25%. The percent decrease was approximately 33%. The percent decrease was approximately 50%. The percent decrease was approximately 66%.

Answers

66% It is 66% because 203 is less than half of 605. So, you would add that together. 203+203=406 Thats not even close to 605 so now you add almost half so that would be about 66%
