# Adding and Subtracting Rational Expressions

posted by .

Iwouldhighly appreciate it if someone could solve these forme.I think I typed themout correctly. What I'm looking at,for instance,the first one,is displayed 5n over 3 times 4n over 3
1.5n/3-4n/3
2.3x/10+9x/10
3.n-2/n+4+8/n+4
4.5m+8/m-1 - m-3/m-1
5.x^2/x-1 - 1/x-1
6.4x+y/2x+3y-2x -2y/2x+3y
7.x^2+3x+2/x^2-16 + 3x++6/x^2-16
8.7/x-5 - 2+x/x-5

hold on, times 4n over 3 or minus?

over

no, I mean 5n/3 MINUS OR TIMES 4n/3?
