Answer :
Convert 7/8 and 4/5 into common denominators using 40; 28/40 and 32/40, multiply those to get 22.4. Divide 7 by 20 to get 0.35. Divide 22.4 by 0.35 for an end quotient of 64.
[tex] \frac{7}{8} * \frac{4}{5} \\\\ \frac{28}{40} \\\\ \frac{7}{10} \\\\ \frac{7}{10} / \frac{7}{20} \\\\ \frac{7}{10}*\frac{20}{7}\\\\ \frac{1}{1} * \frac{2}{1} =2[/tex]
