Proper Fraction
A proper fraction is a fraction in which the numerator is strictly less than the denominator (comparing their absolute values), meaning the fraction's absolute value is less than . When the fraction is positive — for example, , , or — its value lies between and on the number line. When the fraction is negative — such as — its value lies between and . Proper fractions arise naturally when converting a decimal that has no whole-number part (i.e., the digit to the left of the decimal point is ) into fraction form, since the resulting numerator will always be less than the power-of-ten denominator.

When a quality control technician records the weight of a component that is lighter than the standard 1-pound reference, the resulting ratio is a 'proper fraction' because the absolute value of the numerator is ____ than the absolute value of the denominator.
Defining Proper Fractions in Business Reports
In a corporate performance report, a negative fraction (such as -2/3) is correctly identified as a 'proper fraction' if its value is located between -1 and 0 on the number line.
In a professional performance report, data is often expressed as ratios. Match each description of a mathematical property with its correct classification regarding proper fractions.
A data analyst is auditing a series of department efficiency ratios. To correctly label a ratio as a 'proper fraction' in the final report, the analyst must follow a specific verification process based on the mathematical definition. Arrange the following steps in the correct logical order to define and verify a proper fraction.
