Answer 2

Answer:

$\frac{21}{36} \div \frac{30}{44} \\ \frac{21}{36} \times \frac{44}{30} \\ = \frac{ _{7 \: \: } \cancel{ 21}}{_{9 \: \: } \cancel{ 36}} \times \frac{ \cancel{ 44} _{ \: \: 11}}{ \cancel{ 30}_{ \: \: 10} } \\ = \frac{7}{9} \times \frac{11}{10} \\ \boxed{ = \underline{ \underline{ \large \frac{77}{90} }}}$
