A fish tank requires 8 liters of water to fill. Alejandro filled the tank with 2 liters of
water. Anthony poured 1- less than Alejandro into the tank. How much water does the tank
still need for it to be filled?



Answer :

The tank needs 5 more liters of water to be filled.

What is Subtraction?

Subtraction is one of the basic operations of mathematics where we remove numbers or expressions or objects away from a given value.

Amount of water needed to fill the tank = 8 liters

Amount of water Alejandro filled = 2 liters

Amount of water Anthony filled = 1 less than Alejandro = 2 - 1 = 1 liter.

Total amount of water filled = 2 liters + 1 liter = 3 liters

Remaining space can be filled with 8 liter - 3 liter = 5 liters.

Hence tank still need 5 liters of water to be filled.
