3x/4  2x/5 + x/2

So what is to be done?

it is in fraction form & i have to solve i guess.... the mutipul choice answers are as follows in fraction form:
a. x/10
b.3x/10
c.17x/20
d.33x/20
please help me.... 
go and
find the lowest common denominator between the 4, 5 and 2
a common multiple is 20 so..
3x/4  2x/5 +x/2=
5(3x/20) 4(2x/20) + 10(x/20)=
then multiply ...
15x/20  8x/20 + 10x/20=__________ ???
now add and what do you get? 
If the equation is:
(3x/4)  (2x/5) + (x/2)
Common denominator is 20
(15x/20)  (8x/20) + (10x/20) =
combine the three to obtain
17x/20 
~*THANKS*~

17x+5=3(4)
