 3    4


Here we have to divide 7/3 chocolates into 10/4 parts.

First take 7 chocolates and divide it into 3 equal parts.
Now each group of the chocolate becomes 1/3.

And take 10 chocolates and divide it into 4 equal parts.
Now each group of the chocolate becomes 1/4.

So the smallest piece of chocolate in 7/3 is 1/3.
And the smallest piece of chocolate in 10/4 is 1/4.

So, first we will divide 1/3 chocolates into 1/4 parts.
we take 1/3 chocolates and divide it into 1/4 equal parts.
And after division, we get 4 / 3 chocolates from 1/4.

But we have total 7 chocolates of the size 1/3.
So now we will add 4/3, 7 times.
After adding, we get 7 x 4 / 3 chocolates from 7/3.

And we have total 10 chocolates of 1/4 size.
So now we will divide 7 x 4 / 3 into 10 parts.
After division, we get 7 x 4 / 3 x 10 chocolates from 10/4.
