Use any model you choose to find the quotient.

5 divided by 1/2

The answer is 10. I know because I did the (multiplication) division.

When dividing fractions, you're actually multiplying the first number by the reciprocal (the number you get when you switch the numerator and denominator) of the second number. Your original equation looks like this:

5:1/2

The first thing you want to do is find the reciprocal of your second number. In 1/2, the numerator is one and the denominator is two. When you switch the numerator and denominator, you get this:

2/1

Now two is the numerator and one is the denominator.

Next you will multiply 5 by 2/1 (2/1 simplifies to 2)

5*2=10

And there's your answer.
