Multiplying Fractions

Question 1:

\frac{25}{32} \times \frac{4}{15}

\frac{{}^{5}25}{{}_{8}32} \times \frac{4^{1}}{15_{3}} = \frac{5}{24}

Question 2:

\frac{7}{18} \times \frac{45}{49}

\frac{{}^{1}7}{{}_{2}18} \times \frac{45^{5}}{49_{7}} = \frac{5}{14}

Question 3:

\frac{28}{81} \times \frac{18}{35}

\frac{{}^{4}28}{{}_{9}81} \times \frac{18^{2}}{35_{5}} = \frac{8}{45}

Question 4:

\frac{35}{72} \times \frac{40}{63}

\frac{{}^{5}35}{{}_{9}72} \times \frac{40^{5}}{63_{9}} = \frac{25}{81}
