Can anyone help me with rational expressions?

I’m not asking anyone to do homeowk, but I need help on these two styles of problems. The first one asks me to simplify the complex rational expression. It reads as 7/ y^2 +4y+3/ 1/y+3 + 4/y+1. It is 7 over y squared plus, 4y plus 3 over two other fractions 1 over y+3 plus 4 over y+1. Its a fraction over two fractions. I believe I have to factor out the denominators and multiply by the LCD?The second problem asks me to add 8y/ y^2 +12y+27 + 4/y+3. The problem is 8y over y squared plus 12 y , plus 27 plus the fraction of 4 over y+3. I’m sorry that I can’t write this out in fraction form. I’m confused.
