65,438+0% of the goods are transported from warehouse B to warehouse A, at which time the grain reserves of warehouse A and warehouse B are equal.

That is, the grain in warehouse B is divided into four parts, and after it is transported to warehouse A with 1 part, the two parts are equal (now both warehouses have three parts).

It can be known that after warehouse A is transported to warehouse B at 1/4, the ratio of warehouse A to warehouse B is 2: 4.

The raw grain of warehouse A is 2/3/4 = 8/3.

The raw grain of warehouse B is 4-8/3× 1/4 = 10/3.

The raw grain of warehouse A belongs to warehouse B.

8/3÷ 10/3=8/ 10=4/5
