Proper Fraction-Improper Fraction – Definition – Example

Proper and Improper Fractions Proper Fraction: Definition A “Proper Fraction” is a fraction whose numerator is smaller than it’s denominator. Example: In below figure 1/5, is a proper fraction because numerator 1 is smaller than denominator 5. Similarly, 4/9, 3/7 and 5/8 are a proper fractions because every fraction has numerator is smaller than denominator. Some more […]
