Let's firstly convert the mixed fractions to "improper", and then divide,

\bf \stackrel{mixed}{1\frac{3}{4}}\implies \cfrac{1\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{7}{4}}
\\\\\\
\cfrac{7}{4}\div -21\implies \cfrac{7}{4}\div \cfrac{-21}{1}\implies \cfrac{7}{4}\cdot \cfrac{1}{-21}\implies \cfrac{7}{-84}\implies \stackrel{simplified}{-\cfrac{1}{12}}

Hello!

To do this you will simply convert 3/4 to 0.75 and divide.

1.75/-21=1/12.

Our final answer is \frac{1}{12}.

I hope this helps!
