Simplify

1+2/3 over top 2+1/2

My answer

was 2/3 to me it does not seem right If I am wrong please let me know i will put all the steps I did to get this and maybe you can help me see where I did it wrong

2nd question

m^5/4 over top of m^7/16

My answer was 4/m^3

3rd question

3/x-5 +1 over top of 1- 4/x-5

My answer is x-2/x-9

1+2/3 over top 2+1/2

My answer

was 2/3 to me it does not seem right If I am wrong please let me know i will put all the steps I did to get this and maybe you can help me see where I did it wrong

2nd question

m^5/4 over top of m^7/16

My answer was 4/m^3

3rd question

3/x-5 +1 over top of 1- 4/x-5

My answer is x-2/x-9

Lets do the numerator: 1+ 2/3= 5/3

Now the denominator: 5/2

5/3 / 5/2 which is the same as (remember that multiplying the reciprocal is the same as divideing..

5/3 * 2/5 = 5*2/3*5= 2/3 So it is right. Good work.

On the second,

m^5/4 divided by m^7/16 changes to

M^5/4 * 16/m^7 or

m^5/4 * 16* m^-7

4 m^-2 or 4/m^2

Last:

3/(x-5) + 1 or (3+x-5)/(x-5) is numerator.

Now, for denominator,

that changes to (x-5 -4)/(x-5) or

(x-9)/(x-5)

so numerator /denominator changes to a multiply by

numerator * (1/denominator) or

(3+x-5)/(x-5) * (x-5)/(x-9) or

(x-2)/(x-5) and you are correct.
