Practice makes perfect
We want to express 4 liters in gallons.
4 L≈ gal
We can do this by using the fact that 1 gallon equals about 3.79 liters. Let's write this relationship as a unit ratio.
3.79 L/1gal
To perform the conversion, we need to multiply 4 liters by the unit ratio or its reciprocal. Remember, we want to get the capacity in gallons, and every unit we do not want has to be divided out.
We found that 4 liters is equal to about 1.06 gallons. We can now complete the given statement.
4 L≈ 1.06 gal
