Answer 1

$\frac{15}{2} \times \frac{13}{4} - \frac{15}{2} \times \frac{9}{4} \\ = > \frac{15}{2} ( \frac{13}{4} - \frac{9}{4} ) \\ = > \frac{15}{2} \times \frac{4}{4} \\ = > \frac{15}{2} \times 1 \\ = > \frac{15}{2}$

Answer 2

Answer:

Hence, the required solution is -75/8.

Step-by-step explanation:

Given :

$\frac{15}{2} \times \frac{13}{4} - \frac{15}{2} \times \frac{9}{2} \\ → \frac{15}{2} ( \frac{13}{4} - \frac{9}{2}) \\ → \frac{15}{2} ( \frac{13}{4} - \frac{9 \times 2}{2 \times 2} )\\ → \frac{15}{2}( \frac{13}{4} - \frac{18}{4} )$

Then it will be written as follows,

$→ \frac{15}{2}( \frac{ - 5}{4}) \\ → \frac{ - 75}{8}$

Hence, the required solution is -75/8.
