Lets multiply and divide our first fraction by 2 in order to make denominator of both the fractions same.

= $\frac{2}{2}\frac{12}{7d}-\frac{3}{14d}$

= $\frac{24}{14d}-\frac{3}{14d}$

Now taking LCM of both fractions

= $\frac{24-3}{14d}$

Simplifying further

= $\frac{21}{14d} = \frac{3}{2d}$

So out correct answer is $\frac{3}{2d}$
