Today, my mother took me to buy clothes. There are often discounts, such as 20% discount and 10% discount.

Before I learned the proportion, I always thought that 10% discount was the smallest and 10% discount was the largest. But I didn't know until I knew the proportion. A 10% discount is 10%, and a 10% discount is 90%.

In this shop, you get a 10% discount on one dress and a 20% discount on two dresses. So, I chose a dress of 283 yuan and a dress of 244 yuan, both of which were 20% off. So, I made a rough estimate and almost used 450 yuan. So, I calculated in my mind: 283+244=527 (yuan) 527 times 80%= (yuan). Originally, only 42 1.6 yuan was used. How far is it from my estimate? 450-42 1.6=28.4 yuan, with a difference of 28.4 yuan.

The percentage is really good and it saves us a lot of money.

I can't type by bus, so I typed. Please forgive me.
