Multiplying Fractions

Question 1:

\frac{6}{49} \times \frac{7}{48}

\frac{{}^{1}6}{{}_{7}49} \times \frac{7^{1}}{48_{8}} = \frac{1}{56}

Question 2:

\frac{55}{84} \times \frac{49}{60}

\frac{{}^{11}55}{{}_{12}84} \times \frac{49^{7}}{60_{12}} = \frac{77}{144}

Question 3:

\frac{7}{16} \times \frac{16}{35}

\frac{{}^{1}7}{{}_{1}16} \times \frac{16^{1}}{35_{5}} = \frac{1}{5}

Question 4:

\frac{7}{90} \times \frac{9}{14}

\frac{{}^{1}7}{{}_{10}90} \times \frac{9^{1}}{14_{2}} = \frac{1}{20}
