13/100 = 13%
The fraction 13/100, or 13%, can show up in everyday life as a discount, a test score, or a chance of rain. For example, a store might take 13% off an item, or a weather forecast might give a 13% chance of rain.
To picture 13% quickly, imagine 100 equal squares with 13 of them shaded. It is a little more than one-tenth, since 10% is one-tenth and 13% adds three more parts out of 100.
A common mistake is thinking 13% means 13 out of 10 instead of 13 out of 100. Another point of confusion is that a 13% discount does not mean the final price is 13%; it means the price is reduced by that amount.
