15/75 = 20%
A value of 15/75, or 20%, can show up in everyday life as a discount, a test score, or a survey result. For example, a store might take 20% off a jacket, or 20 out of every 100 people might prefer one brand.
You can picture 20% as one-fifth of a whole, since a whole divided into five equal parts has one part representing 20%. It is also easy to estimate by imagining 20 objects out of a group of 100, or about 2 objects out of every 10.
A common mistake is thinking 15/75 represents 15%, simply because the numerator is 15. The denominator matters because it tells you the total amount, so 15 out of 75 is a much larger share than 15 out of 100.
