In dividing a mixed number by a proper fraction, here are the steps:

1. Convert the mixed number to an improper fraction first.


2(3)/(4)=((2*4)+3)/(4)=(11)/(4)

2. Get the reciprocal of the divisor or the proper fraction.


(2)/(5)\rightarrow(5)/(2)

3. Change the operation from division to multiplication.


(11)/(4)*(5)/(2)

4. Multiply the two numerators and the two denominators.


(11)/(4)*(5)/(2)=(55)/(8)

5. Simplify the answer. In this case, the answer is an improper fraction. Let's convert it to a mixed number and simplify.


(55)/(8)=6(7)/(8)

The answer is 6 7/8.
