It works the same way as riding a bike. When you need to go up a hill, you switch the chain to low gear, and you pedal faster to go the same speed but it’s easier on you. The gear ratio is low, because it takes more turns with your feet (numerator) to complete a full turn of the back wheel (denominator) than it would if you were in high gear.
