Here we have to divide 18/8 chocolates into 20/2 parts.

First take 18 chocolates and divide it into 8 equal parts.
Now each group of the chocolate becomes 1/8.

And take 20 chocolates and divide it into 2 equal parts.
Now each group of the chocolate becomes 1/2.

So the smallest piece of chocolate in 18/8 is 1/8.
And the smallest piece of chocolate in 20/2 is 1/2.

So, first we will divide 1/8 chocolates into 1/2 parts.
we take 1/8 chocolates and divide it into 1/2 equal parts.
And after division, we get 2 / 8 chocolates from 1/2.

But we have total 18 chocolates of the size 1/8.
So now we will add 2/8, 18 times.
After adding, we get 18 x 2 / 8 chocolates from 18/8.

And we have total 20 chocolates of 1/2 size.
So now we will divide 18 x 2 / 8 into 20 parts.
After division, we get 18 x 2 / 8 x 20 chocolates from 20/2.
