I really need the answer. Thanks to who'll help me.

Answer:
125 and 0.292
Step-by-step explanation:
Think about it as a system of equations:
1)
[tex]a+b=125 +1/3\\a=125.33-b\\\\2) ab=36+1/2\\[/tex]
at this point you can insert the equation you got from 1.
[tex](125.33-b)b=36.5\\125.33b-b^2=36.5\\b^2-125.33b+36.5=0[/tex]
with this form, you can use the quadratic equation to find your two possible answers.
following the quadratic equation we find that our answers are 125 and 0.292
