2000 L

Step-by-step explanation:

There are 1250 L of water in a tank at present. If the tank is 0.625 full, what is the capacity of the tank?

The simple solution is:

1250 L ÷ 0.625 = 2000 L

The algebraic solution is:

Let c equal the capacity of the tank.

Therefore, c × 0.625 = 1250.

Divide both sides by 0.625:

c × 0.625 ÷ 0.625 = 1250 ÷ 0.625

And simplify:

c = 1250 ÷ 0.625

c = 2000
