[tex] \frac{9}{20} [/tex] divided by [tex] \frac{4}{15} [/tex]

is the same as 

[tex] \frac{9}{20}* \frac{15}{4} [/tex]

Now you just have to multiply the top by each other and the bottom by each other so 
[tex] \frac{9*15}{20*4} [/tex]

== [tex] \frac{135}{80} [/tex]

== [tex] \frac{27}{16} [/tex] 

Mixed Fraction would be [tex]1 \frac{11}{16} [/tex]
and Decimal would be 1.6875
