Hello!

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

1.75/-21=1/12.

Our final answer is
(1)/(12).

I hope this helps!

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


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