Initially, 1/4 of the tank was filled.
After adding 12 gallons, it was 3/4 full.
Increase in fuel filled portion =

So 2/4 of the tank = 12 gallons
1/4 of tank = 12 ÷ 2 = 6 gallons
4/4 of tank = 6×4 = 24 gallons
____________________
Portion remaining to be filled =

Fuel needed = 1/4 × 24 = 6 gallons
So you need 6 more gallons to fill the tank

Exact numbers are numbers are exact (and therefore have an unlimited number of significant figures)
<h3>What are exact numbers?</h3>
Exact numbers can be defined as numbers known with complete certainty.
These numbers have zero uncertainty and have infinite values.
Some examples of exact numbers are:
- counted numbers of objects or certain unit conversions such as 3 feet in 1 yard, exactly 12 eggs in a dozen
We can see that exact numbers have infinite values and thus have unlimited number of significant figures.
