Answer:
15 girls, 10 boys
Step-by-step explanation:
Since the ratio is 3:2, then the ratio can be rewritten as 15:10. So there are 15 girls and 10 boys
You want to make the denominator of the fractions to be equal to each other.
(2/n+8)+(4/n+1) multiply n+1 by n+8, and multiply n+8 by n+1
(4n+32/n^2+8)+(2n+2/n^2+8) Now that the denominators are equal we can solve the numinator by adding like terms.
4n+2n=6n, 32+2=34
Your final answer is 2(3n+17)/n^2+8
Answer:
2.75 or 2 3/4
Step-by-step explanation:
1 + 1 = 2
1/4 + 1/2 = 3/4
1/4 = 1/4
make 1/2 into 2/4
add 1/4 to 2/4
3/4
2 + 3/4 = 2 3/4 or 2.75
