What is 1/20 as a percentage? It equals 5.00%. This small fraction shows up a lot when you split something into twenty equal parts and take just one of those parts.
In everyday life, 5 % can represent a tiny discount, a modest tip, or a minor increase in a score. Because it is such a low percentage, it is easy to notice when something changes by that amount.
Remember that 5 % means “five out of every hundred,” which is the same as one out of twenty. Whenever you see a fraction like 1⁄20, you can think of it as a simple 5 % in your mind.
