a/b divided by c/d=a/b time d/c
the reason it works is
you have
\(\frac{ \frac{4}{9} }{ \frac{1}{3} }\)
fractions in the denomenator is scary
make it one
remember that a/b times b/a=1 so 1/3 times 3/1=1
times the whole thing by 1 to keep is same
\(\frac{ \frac{4}{9} }{ \frac{1}{3} }\) times \(\frac{ \frac{3}{1} }{ \frac{3}{1} }\)=
\(\frac{ (\frac{4}{9})(\frac{3}{1}) }{ (\frac{1}{3})(\frac{3}{1}) }\)=
\(\frac{ \frac{12}{9} }{ \frac{3}{3} }\)=
\(\frac{ \frac{12}{9} }{ 1}\)=
12/9=4/3
reault is 4/3
