Answer:

5 divided by (-3)

Step-by-step explanation:

5 3/4 is equals to:

\frac{5*4}{4} + \frac{3}{4} = \frac{23}{4}.

-3 3/8 is equals to:

\frac{-3*8}{8} - \frac{3}{8} = -\frac{27}{8}.

The division of two fractions is the multiplication of the first one divided by the inverse of the second one. So:

\frac{\frac{23}{4}}{-\frac{27}{8}} = -\frac{23}{4}*\frac{8}{27} = \frac{46}{27} = 1.70

As for the answers, we have that:

6 divided by (-3) is -2.

6 divided by (-4) is -1.5.

5 divided by (-3) is -1.67.

5 divided by (-4) is -1.25.

So the best estimation for -1.70 is:

5 divided by (-3)
