4/5x+1/2x=

Question

i know the answer is 13/10x but I dont know how to get that the steps

Answer 1

4/(5x) + 1/(2x) =

 

4*2/(2*5x) + 1*5/(5*2x) =

 

8/(10x) + 5/(10x) =

 

13/(10x)

Answer 2

 4/5 X + 1/ 2 X =

 

  Very simply adding 2 fractions/ 4th grade

 

 

  ( 4/ 5 + 1/ 2 ) X =

    

  Make the denominators the same ( common denominator).

   

    (8/10 + 5/ 10 ) X  =

 

     (13/ 10 ) X

Answer 3

(4/5)x + (1/2)x = (8/10)x + (5/10)x = (8+5)/(10)x = (13/10)x 

 

The key is to make sure the denominators are the same. 10 is a multiple of 5 and 2, so convert 4/5 to 8/10 and 1/2 to 5/10 before adding. 

 

Hope it helps!
