11 1/4 miles
112 1/2 miles.
202 1/2 miles
405 miles

405 miles

Step-by-step explanation:

Take the miles per gallon and multiply the gallons to get the miles

22.5 * 18

405 miles

202 1/2 miles

Step-by-step explanation:

We want to find how far she can drive on 1/2 a tank of gas.

Her tank can hold 18 gallons. Multiply 18 and 1/2, or divide 18 by 2.

18*1/2=18*0.5=9

or

18/2=9

1/2 a tank of gas is 9 gallons. Now, we need to find how far she can drive. Multiply the number of gallons in 1/2 a tank by the miles per gallon.

gallons in 1/2 tank * miles per gallon

We know she has 9 gallons in 1/2 tank, and she gets 22 1/2, or 22.5 miles per gallon.

9 gallons * 22.5 miles/gallon

9*22.5=202.5= 202 1/2

She can drive 202 1/2 miles on 1/2 a tank of gas.
