Dimensional analysis

(11.38 g/day)*(2.82ug/kg)*(17.5kgday/mg)/20kg
= 0.000000002808015
What would be the symbols after the number g/kg, ug/kg? I have no clue
Please help

I don't know what you want.
I see that in the numerator you have the following units:
g*ug*kg*day
and in the denominator
day*kg*mg*kg
That on itself makes not a lot of sense to me.
What are you trying to do?

(11.38 g/day)*(2.82ug/kg)*(17.5kgday/mg)/20kg
Just looking at the numbers:
11.38 * 2.82*17.5/20
=561.603/20
=28.08015
But what should I have as the extension
g/kg or what? 
reread my response, and examine the units in the numerator and denominator.
