Question 1089683
<pre>
a = (2/3)b    (1)
ab = 24       (2)
</pre>

(2/3)b*b = 24
       b*b = 36
           b = +/-6

Discard the negative potential solution because problem statement says "positive number."
b=6 —> a=4

Ans:   4 + 6 = 10   (edited to provide the sum)   
—
Check:   (2/3)*6 = 12/3 = 4   (ok)
            4*6 = 24 (ok)
