Multiply the two. The units will cancel out. 22 miles per gallon can be expressed as 22 miles / 1 gallon, so you can write the following: 18 gallons * 22 miles / 1 gallon Which simplifies to 18 * 22 miles = 396 miles.
Answer: 18*22=396 ;
You can drive 396 miles on one tank of gas if your tank holds 18 gallons and your vehicle gets 22 miles per gallon. This is calculated by multiplying the number of gallons in the tank by the miles per gallon. Therefore, 18 gallons multiplied by 22 miles per gallon equals 396 miles.
