Hi! To find the capacity of the tank that is remaining, we would subtract 4/5 from 1 (1 would represent the whole tank).

**1 - 4/5 = 1/5**

We need to fill up the remaining 1/5 of the tank.

To find the total capacity of the tank in pounds, we would divide the pounds needed (40) by 1/5.

**40 / (1/5) = 40 * 5 = 200 pounds**

**The capacity of the tank is 200 lbs. **
