Answer:

It will take 3.7 gallons of gasoline to fill up the tank. You will need to use division.

Step-by-step explanation:

You take the full 14.5 gallons and divide it by 4 that will get you the last fourth of a whole to fill up the gallon. When you divide, you get exactly 3.625 but rounding up to 3.7 will completely fill up the tank.

Because the tank can take 14.5 gallons of gas, it would need an additional 3.625 gallons to fill it up.

The tank has a capacity of 14.5 gallons and 3/4 of this is full.

You need to find the number of gallons of gas in the tank:

= Capacity of tank x Proportion that is filled

= 14.5 x 3/4

= 10.875 gallons

The amount of gallons needed to fill it up is:

= Capacity of tank - gallons of gas inside tank

= 14.5 - 10.875

= 3.625 gallons

In conclusion, 3.625 gallons are needed to fill the tank.
