How do you apply decimals in your every day life?

Answer 1

Decimals are used on a daily basis by everyone. For example, if you go to the store a purchase items totaling $8.43, that is using decimals in the 43 cents whether you give the cashier the exact amount or if you give him or her $9 for the purchase. If you give $9 for the purchase, your change will be 57 cents, which is the second use of decimals in the same purchase.

Also, canned items purchased at the grocery store often come in weights, such as a can of tomatoes that weighs 28.8 ounces. When shopping the sale racks, that is using decimals, too. When a sale sign shows items on sale for 25% off, that's the same as .25 off the regular price.

They are also used in cooking, such as a recipe that calls for 1 1/4 cup of sugar, which is 1.25 cups of sugar, or one which calls for 1/2 cup of milk, which is .5 cups of milk.

Many people wear shoes that are a "half size", such as a size 7 1/2, which is the same as 7.5, which is also a decimal.
