Multiplying Fractions

Question 1:

\frac{7}{40} \times \frac{16}{49}

\frac{{}^{1}7}{{}_{5}40} \times \frac{16^{2}}{49_{7}} = \frac{2}{35}

Question 2:

\frac{8}{49} \times \frac{7}{24}

\frac{{}^{1}8}{{}_{7}49} \times \frac{7^{1}}{24_{3}} = \frac{1}{21}

Question 3:

\frac{7}{25} \times \frac{5}{14}

\frac{{}^{1}7}{{}_{5}25} \times \frac{5^{1}}{14_{2}} = \frac{1}{10}

Question 4:

\frac{21}{88} \times \frac{40}{63}

\frac{{}^{1}21}{{}_{11}88} \times \frac{40^{5}}{63_{3}} = \frac{5}{33}
