1. There are two containers, one large and one small, and the ratio of water in the two containers is 7 to 3. Pour the water from the big container into the small container. There is as much water in both containers. How many liters of water are there in each container?

The total amount of water has not changed:

Before the decline: big: small = 7: 3.

After inversion: large: small = 1: 1 = 5: 5.

Each serving: 12/(7-5)=6 (liter)

Capacity: 6x7=42 (liter)

Trumpet: 3x6= 18 (length)

2. Distribute a batch of goods to Party A and Party B for transportation according to the ratio of 5: 3. Because of an emergency, team A handed over one-fifth of the tasks to team B for transportation. It is known that Team B * * * has transported 48 tons, so what is the original transportation task of Team A?

Distribute a batch of goods to Party A and Party B for transportation according to the ratio of 5 to 3.

Assigned one; 5/8 to 3/8.

Because of an emergency, team A handed over one-fifth of the tasks to team B for transportation.

(5/8)x 1/5= 1/8

B * * * shipment:

3/8+ 1/8= 1/2. It is known that team B * * * has transported 48 tons. Then the goods are:

48/( 1/2)=96 (ton)

Assigned one; 5/8:

96x(5/8)=60 (ton)

Team A's original transportation task was 60 tons.
