\(\frac{9}{20}\) divided by \(\frac{4}{15}\)
is the same as
\(\frac{9}{20}* \frac{15}{4}\)
Now you just have to multiply the top by each other and the bottom by each other so
\(\frac{9*15}{20*4}\)
== \(\frac{135}{80}\)
== \(\frac{27}{16}\)
Mixed Fraction would be \(1 \frac{11}{16}\)
and Decimal would be 1.6875
