Answers:

1. 4a^3x^2/6a^4=2*2*a*a*a*x*x/2*3*a*a*a*a=2*x*x/3*a=2x^2/3a

2. 3a/4x

3. 3a^2x/4y^4

4. 3x/4y

5. 3y^2z/2

6. 2*2*2*a*a*b/(2*2*3*a*b*b+2*2*a*b*c)=2*2*2*a*a*b/2*2*a*b*(3*b+c)=2*a/(3*b+c)=2a/(3b+c)

in this problem you need to factor like terms out of the denominator using the techniques you learned in the lessons on factoring.

7. 2acx(ax+1)/2*5*a*c*c*x=(ax+1)/5c

8. 5ab(a+b)/5ab(c+d)=(a+b)/(c+d)
