Ratios, proportions, and algebraic thinking for sixth grade students.
Shopping is a great place to use proportions! When there’s a sale, you can use proportions to figure out new prices, or to compare which deal is better.
If something is 25% off, you can set up a proportion to find out how much you save.
Use proportions to compare the cost per item in different-sized packages and find the best deal.
Next time you shop, try using proportions to make your money go further!
A $40 shirt is 25% off. Use proportions to find the new price: \( \frac{25}{100} = \frac{x}{40} \).
A 12-pack of juice costs $6 and an 8-pack costs $4. Use proportions to find the price per juice and see which is a better buy.
