Would some one look at these problems and see if I got them right Thanks Just let me if they are wrong so I can go back over them

1.Write in simplest form 48/56

A. 6/7

2.Multiply 8x^3/5 *10/x^3

A. 16/x^4

3.Divide 4/x^7 / 12/x^3

A. 1/3x^2

4. divide x^2-36y^2/5x^2+30y / (x^26xy)

A. (x+6y)/(5x)(x^2+6y)

5.Subtract. Express your answer in simpliest form

3x/14-x/14

A. x/7

6.Add. Express your answer in simplest form. x^2/x+1 + 5x+4/x+1

A. x+4

7.Add. Express your answer in simplest form.

2x/x^2+15x+54 + 4/x+6

A. 6/x+9

8.Solve. x/7 - 1/2 = x-11/2

A. x=14

9.solve 9/x-5 -1= 8/x+5

A. x= -10 and 11

10.Solve 2/3 = 12/x

11. Simplify 6/8 over 2/18

A.39/4

1.Write in simplest form 48/56

A. 6/7 **OK**

2.Multiply 8x^3/5 *10/x^3

A. 16/x^4 **NO**

3.Divide 4/x^7 / 12/x^3

A. 1/3x^2 **NO**

4. divide x^2-36y^2/5x^2+30y / (x^26xy)

A. (x+6y)/(5x)(x^2+6y) **I can't tell what the problem is.**

5.Subtract. Express your answer in simpliest form

3x/14-x/14

A. x/7 **OK**

6.Add. Express your answer in simplest form. x^2/x+1 + 5x+4/x+1

A. 6/x+9 **I don't know what the problem is.**

8.Solve. x/7 - 1/2 = x-11/2

A. x=14 **OK if the problem is
(x/7)-1/2 = (x-11)/2**

9.solve 9/x-5 -1= 8/x+5

A. x= -10 and 11

**I don't know the problem.**

10.Solve 2/3 = 12/x

A. x=18

**OK**
