Examples of decimals in real life?
One of the most common instances will be money! Whenever we have some number of cents that do not add up to a full dollar, we express the amount as a decimal. For example, $3.75, $12.69, and even $1.00 are all examples of decimals. Decimals are also used in measurements of all types. You might be told to take 2.5 tablespoons of a medicine twice per day, have a weight of 95.1 pounds, have to buy carpeting for a room measuring 12.3 x 16.8 feet, etc. Decimals are frequently used in science, from laboratory experimental data to certain well-known scientific constants (for instance, g is often treated as 9.8 ms^-2 and Avogadro's number for the number of particles per mole is approximately 6.02 x 10^23).
