\boxed{(a)/(b)/(c)/(d)=(a)/(b)\cdot(d)/(c)}\\\\10(1)/(2)/3(1)/(5)\\\\\text{convert mixed numbers to an improper fractions}\\\\10(1)/(2)=(10\cdot2+1)/(2)=(21)/(2)\\\\3(1)/(5)=(3\cdot5+1)/(5)=(16)/(5)\\\\10(1)/(2)/3(1)/(5)=(21)/(2)/(16)/(5)=(21)/(2)\cdot(5)/(16)=(21\cdot5)/(2\cdot16)=(105)/(32)=3(9)/(32)\to\boxed{B}
