I'm trying to help my son with his simplifying algebraic fractions and i need help.Can someone please help me?

Question

3a+b

------- =

6a+2b

2x+8

------- =

x+4

Answer 1

okay, so for the first one

6a +2b is equal to twice 3a+b.  So, 6a +2b is equal to 2 (3a+b)

(3a+b)/2(3a+b)= 1/2 or 0.5 (they are the same thing)

The 3a+b cancel out.

for the next one,

2x+8 is equal to twice x+4.  So, 2x+8 is 2(x+4)

2(x+4)/ (x+4)= 2 since the x+4 cancel out.

Answer 2

3a+b              

-------    =        

6a+2b          

3a+b                

-------    =    

2(3a+b)    

    1

------

    2    

cancel numerator to the denominator on the parenthesis because they are both the same....

so the answer is 1/2 one half.....

2x+8          

------- =      

x+4            

2(x+4)        

----------- =      

  x+4    

    2

----=        2

    1        

cancel numerator to the denominator on the parenthesis because they are both the same....

Answer 3

3a+b             3a+b

--------=        ----------  = 0.5

6a+2b         2(3a+b)

2x+8       2(x+4)

-------- =    --------- = 2

x+4              x+4

Answer 4

a+b

------

2a+2b

2x+2

-------

x
