Answer 1

Charlotte's car used \frac{1}{90}​ of a gallon to travel \frac{1}{2} ​ of a mile. How many miles can the car go on one gallon of gas?

Answer:

The car go 45 miles on one gallon of gas

Step-by-step explanation:

From the above question

1/90 gallons of gas = 1/2 mile

1 gallon of gas = x mile

Cross Multiply

1/90 × x = 1/2 × 1

x = 1/2 / 1/90

x = 1/2 × 90/1

x = 45 miles

Hence:

The car can go 45 miles on 1 gallon of gas.
