71/355 = 20%
A fraction like 71/355, or 20%, can show up in everyday life when one out of every five items meets a certain condition. For example, a store might report that 20% of its customers used a coupon, or a teacher might say that about 20% of the class was absent.
To picture 20% quickly, imagine dividing a group into five equal parts and focusing on one part. It is also close to one-fifth, so in a group of 100 people, you would expect about 20 people.
A common mistake is thinking 20% means 20 out of 20, when it actually means 20 out of 100. Another point of confusion is treating 20% as exactly the same as “one-fifth” in every situation, even though this fraction has been reduced to that same value.
