To simplify the expression \frac { 3a } { 2a b }  \frac { 2a } { 4}, we can follow these steps:

Simplify the second fraction by dividing both the numerator and denominator by 2: \frac { 2a } { 4} = \frac { a } { 2}

Now, we have the expression \frac { 3a } { 2a b }  \frac { a } { 2}.

To combine the fractions, we need a common denominator. The common denominator is 2ab.

Multiply the first fraction by \frac { b } { b } to get the common denominator: \frac { 3a } { 2a b } = \frac { 3ab } { 2ab }

Now, we have the expression \frac { 3ab } { 2ab }  \frac { a } { 2}.

Combine the fractions by subtracting the numerators: \frac { 3ab  a } { 2ab }

Simplify the numerator by factoring out the common factor of a: \frac { a(3b  1) } { 2ab }

Finally, simplify the expression by canceling out the common factors: \frac { 3b  1 } { 2b }
