29/145 = 20%
A value like 29/145, or 20%, can show up in everyday situations such as a sale discount, a survey result, or a classroom attendance rate. For example, if about one-fifth of customers choose a certain product, that group could represent 20% of the total.
You can picture 20% as one out of every five equal parts. It is also easy to estimate as “about a fifth,” which helps you quickly judge whether a group or amount seems close to that size.
A common mistake is thinking 20% means 20 items rather than 20 parts out of every 100. The actual number of items depends on the total, so 20% of 50 is different from 20% of 500.
