Question

What is the Quotient of 1 and 2/3 divided by 2 and 3/5

Answer 1

25/39

Explanation:

For division of mixed numbers, it often works well to first convert them to improper fractions. Then the division proceeds in the usual way: "invert and multiply", or "dot, swap."

__

`1(2)/(3)/2(3)/(5)=(5)/(3)/(13)/(5)=(5)/(3)\cdot(5)/(13)\\\\=(5\cdot5)/(3\cdot13)=\boxed{(25)/(39)}`
