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 :)
