A percentage is a way of expressing a fraction or proportion as a number out of 100. It is often represented by the symbol "%". For example, if you have 20 out of 100 marbles, that would be written as 20%.

To calculate a percentage, divide the number you want to find the percentage of by the total and then multiply by 100. For example, if you want to find out what percentage of 200 is 50, you would divide 50 by 200 and then multiply by 100, giving you 25%.

A sales story problem is a type of word problem that involves using percentages to solve a real-world scenario related to buying or selling goods or services. These problems often involve calculating discounts, markups, or sales tax.

Percentages are commonly used in sales to calculate discounts or markups on products. For example, if a store is having a 20% off sale, you would calculate the discounted price by multiplying the original price by 0.8 (100% - 20%). Percentages can also be used to track sales growth or determine profit margins.

Understanding percentages in sales is important for both consumers and businesses. For consumers, it allows them to calculate discounts and make informed purchasing decisions. For businesses, it helps with pricing strategies and determining profit margins. Additionally, understanding percentages can help with financial planning and budgeting.
