SVEN [57.7K]

Answer:

Step-by-step explanation:

Let's take the numerator first

3 1/2 - 9 3/4

Convert to improper fraction

7/2 - 39/4

Find the LCM

$\frac{14 - 39}{4}$

= -25/4

Now let's take the denominator

-2.5

Convert to fraction

-5/2

Combine the two parts of the fraction

-25/4 / (-5/2)

This becomes;

-25/2 * -2/5

= +5
