Well, is namely their difference, so, let's first convert the mixed fractions to "improper", and subtract.

$\bf \stackrel{mixed}{30\frac{1}{2}}\implies \cfrac{30\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{61}{2}}
\\\\\\
\stackrel{mixed}{100\frac{3}{4}}\implies \cfrac{100\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{403}{4}}\\\\
-------------------------------\\\\
\cfrac{61}{2}-\cfrac{403}{4}\impliedby \textit{so our \underline{LCD is 4}}\implies \cfrac{(2\cdot 61)~-~(1\cdot 403)}{4}
\\\\\\
\cfrac{122-403}{4}\implies \cfrac{-281}{4}\implies -70\frac{1}{4}$

Arjun solved the equation 7·=56. His work is shown.

Arjun should have divided both sides of the equation by 7 instead of multiplying.
