1/20 = 5%
A value like 5% can show up as a small discount, a tip, or a chance of rain in a weather forecast. It’s a modest amount, but it can still matter when the price or total is large.
To picture it quickly, imagine one shaded square in a grid of 20 equal squares. It’s about one out of every 20 items, or a small sliver of a whole.
A common mix-up is thinking that 5% means taking $5 off any price. It actually describes a share of the total, so the amount changes depending on what the total is.
