6!2!/3!1!

7!9!/2!7!

3!4!/1!3!

5!4!/2!5!

Answer 1

$\frac{6!2!}{3!1!}= \frac{6.5.4.3.2.2}{3.2}= 6.5.4.2= 240$

$\frac{7!9!}{2!7!}= \frac{9!}{2!}= \frac{9.8.7.6.5.4.3.2}{2}= 9.8.7.6.5.4.3=181440$

$\frac{3!4!}{1!3!}= \frac{4!}{1!}= 4.3.2=24$

$\frac{5!4!}{2!5!} = \frac{4!}{2!}= \frac{4.3.2}{2}= 4.3= 12$
