Question

If a gas tank can hold 30 gallons, how many gallons does it contain when it is three-fifths full?​

Answer 1

3/5 of 30 = (3/5)*30

3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/5

3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/5

3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/53/5 of 30 = 18

3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/53/5 of 30 = 18So when the tank is 3/5 full, there are 18 gallons in the tank.
