For the two terms: on the LHS and on the RHS for being equal they must be an integer.
We can cross multiply
\(4a=3b\)
This means that a is a multiple of 3 and b is a multiple of 4. The two quantities must balance
As such, \(b = 4\) and \(a =3\).
Then \(\frac{2a-b}{b}=\frac{a}{a+b}\)
Substitute
\(\frac{6-4}{4}=\frac{3}{4+3}\)
\(\frac{2}{4}=\frac{3}{7}\)
\(\frac{2}{4} > \frac{3}{7
}\)
A is the answer
