a 64 gallon tank contains 45 gallon of oil. how many gallons are removed if fourfifths of this quantity is sold
4/5 * 45 = 36
A 64 gallon tank contains 45 gallons of oil. How many gallons are removed if four-fifths of this quantity is sold?
To find out how many gallons are removed when four-fifths of the oil is sold, we need to calculate four-fifths of 45 gallons.
To do that, we multiply 45 by four-fifths:
45 * 4/5 = 36 gallons
Therefore, if four-fifths of the oil is sold, 36 gallons will be removed from the tank.
