Q:

# Where do people find decimals in real life?

A:

People find decimals in many places during daily life: on price tags of items at clothes stores, on bank credit card statements and even on food nutrition labels. Decimals exist in many places and play an important role in daily life. Small changes in decimal placements lead to big changes in price, quantity, expenditures and savings.

Decimals exist in two forms: terminating and repeating. Terminating decimals end upon reaching a set point, typically after reaching one, two or three successive decimal places. Repeating decimals, in contrast, lack a set end point. They contain a repeating single digit or group of digits and extend infinitely. Most decimals encountered during daily life classify as terminating decimals. Prices on clothes, personal accessories and food products are expressed as numbers followed by one or two decimal places. Decimals can also reveal important financial information, such as the total amount of earnings in checking and savings accounts at financial institutions.

Decimals are also present on food labels and are used to indicate the quantity of certain food components, such as fats, cholesterol, sugar, vitamins, carbohydrates and fiber. Knowing the amount of these nutrients in a serving size lets consumers calculate daily consumption.
