Abdul drove 420 miles using 18 gallons of gas. At this rate, how many gallons of gas would he need to drive 357 miles?
To find the number of gallons of gas needed to drive 357 miles, we can set up a proportion:
Miles driven / Gallons of gas = Miles to drive / x Gallons of gas
Using this proportion, we can fill in the given information:
420 miles / 18 gallons of gas = 357 miles / x gallons of gas
To solve for x, we can cross multiply:
420x = 18 * 357
Dividing both sides of the equation by 420:
x = (18 * 357) / 420
x = 15.3
So Abdul would need approximately 15.3 gallons of gas to drive 357 miles.
