How are decimals used in everyday life?

The main use I can think of is in money. Money is expressed in decimal form.

Although for everyday use, we rely on inches, feet and yards for distance, other countries use decimal measures — millimeters, centimeters, meters and kilometers. Likewise, other measures in other countries and many scientific measures rely on the decimal system. For example, liquid medications are administered in cc (cubic centimeters) by volume.

This is just a beginning. I hope this helps. Thanks for asking.

Decimals are used in a wide range of everyday situations. Here are a few examples:

1. Money: Decimals are essential in currency systems worldwide. In most countries, currency is expressed in decimal form, with dollars and cents. For example, $3.50 represents three dollars and fifty cents.

2. Measurements: In many countries, measurements such as length, mass, and volume are often expressed in decimal form. For instance, the metric system uses millimeters, centimeters, meters, and kilometers. Similarly, weight measurements like grams and kilograms are based on decimals.

3. Cooking and Baking: Recipes often require precise measurements, and decimals are used for accurate proportions of ingredients. For example, 1.5 cups of flour or 0.25 teaspoons of salt.

4. Time: Time can be expressed in decimals as well. For example, a half-hour can be represented as 0.5 hours or 30 minutes.

5. Sports: Decimals are commonly used in sports to measure performance. For instance, in track and field, athletes' times or distances are often recorded to the hundredth or thousandth of a second or meter.

6. Grades and Statistics: Decimals are used to represent percentages, grading systems, and statistical data, such as test scores, averages, and research findings.

Overall, decimals are integral to many aspects of our daily lives, providing precision and accuracy in measurements, calculations, and transactions.
