ways decimals are in everyday life

Decimals are easier to work with mathematically than fractions.
If your room is 13 1/4 feet wide -- its easier to change that to 13.25 when you want to find the area of the room.
Decimals are used in many different ways in everyday life. Here are a few examples:
1. Money: Decimals are essential when dealing with money. For instance, when you go shopping, prices are often displayed with decimal values, such as $9.99. When you make a payment, you need to add up the prices and calculate the total using decimals.
2. Measurements: Decimals are used to represent measurements. For example, a recipe might call for 0.5 cups of flour or 1.25 liters of water. In construction, decimal measurements are used to determine the length, width, and height of objects or spaces.
3. Grades: In the educational system, decimal grades are commonly used to evaluate students' performance. For instance, an assignment might be graded as 8.5 out of 10, or a student's average grade could be 87.6%.
4. Sports: Decimals are used in many sports to measure performance. For instance, in track and field events, decimal times are used to record the time taken to complete a race. In swimming, decimal times are used to measure lap times or finishing times.
5. Science and Engineering: In scientific and engineering fields, decimals are used to represent precise measurements. For example, scientists often use decimal notations for measurements of weight, distance, temperature, or time.
To get a better understanding of how decimals are used in everyday life, try observing your surroundings and thinking about how decimal values might be present in different contexts.
