Jim drove 436 miles using 16 gallons of gas. at this rate, how many limes would he drive using 14 gallons of gas?

The ratio here is 16:436.
The easiest way to solve this is finding how many miles Jim can drive using just 1 gallon. We can do this by dividing both sides of the ratio by 16.

16÷16 is 1
436÷16 is 27.25
so our new ratio is 1 gallon:27.25 miles.

next we simply multiply both sides by 14.
1x14=14
27.25x14=381.5 miles :)
