Dividing Fractions

Question 1:

\frac{4}{45} \div \frac{44}{81}

\frac{{}^{1}4}{{}_{5}45} \times \frac{81^{9}}{44_{11}} = \frac{9}{55}

Question 2:

\frac{9}{40} \div \frac{27}{35}

\frac{{}^{1}9}{{}_{8}40} \times \frac{35^{7}}{27_{3}} = \frac{7}{24}

Question 3:

\frac{14}{45} \div \frac{77}{90}

\frac{{}^{2}14}{{}_{1}45} \times \frac{90^{2}}{77_{11}} = \frac{4}{11}

Question 4:

\frac{5}{18} \div \frac{25}{27}

\frac{{}^{1}5}{{}_{2}18} \times \frac{27^{3}}{25_{5}} = \frac{3}{10}
