2/4 is larger than 2/8, so we know our answer will be a fraction; part of a whole number.

We can simplify 2/8 into 1/4, as well as 2/4 into 1/2.

Now our question is simply how many times 1/2 goes into 1/4.

1/4 ÷ 1/2

We can go ahead and turn it into a multiplication problem using keep switch flip.

Keep  Switch  Flip

 1/4        x       2/1

1/4 x 2/1

And now cross simplify.

1/2 x 1/1

And solve

2/1 x 1/1 = 1/2

1/2 is a fraction, confirming our prediction.
