He sold 3/5 in the morning. So I shaded 3 units at first. You can observe from the darker line. Then he sold 1/4 of the remainder. Since the remainder as only 2 parts, you have to cut them into 4 parts to get the quarter. And you have to cut all the units as well. That’s why from 5units it becomes 10 units

You have to divide by 2 so that the remainder can have 4 units and you can take 1/4 from the remainder
