5/10 = 50%
A value like 50% shows up in everyday life when a store offers half off or when a weather forecast says there’s an even chance of rain. It can also describe being halfway through a movie, a school year, or a full tank of gas.
Picture 5/10 as five shaded pieces out of ten equal pieces, or as one half of a whole. For a quick estimate, think of splitting something into two equal parts and taking one of them.
A common mix-up is thinking 50% off means the final price is 50% of the original price plus another discount. It means half the original price is taken off, so half remains.
