Who uses decimal numbers?

Decimal numbers are used in a wide range of fields and professions due to their versatility in expressing precise quantities and measurements.

Fashion designers may use decimal numbers in sizing and measurements when creating patterns, ensuring that fabrics fit together perfectly, or when calculating fabric quantities needed for a design.

Scientists extensively use decimal numbers in their work to represent measurements, perform calculations, and express data—whether in chemistry, physics, biology, or any other scientific discipline. Precision is crucial in scientific experiments and data analysis, making decimal notation essential.

Chefs also rely on decimal numbers when measuring ingredients, especially when precision is key to the outcome of a recipe. For example, a recipe might call for 2.5 cups of flour, where using a decimal helps in making accurate measurements for cooking.

Given that each of these professions utilizes decimal numbers for accurate representation and calculations, it is evident that the correct answer encompasses all of them. This demonstrates the broad applicability and necessity of decimal numbers in various fields.
