6 Proper, Improper, Mied Fractions. Proper fractions Improper fractions Mied fractions Its factor is smaller than its denominator. Eamples: Its factor is larger than its denominator. Eamples: A combination of a whole number and a proper fraction. Eamples: Converting Mied Fractions to Improper Fractions To convert a mied fraction to an improper fraction, follow these steps: Multipl the whole number part b the fraction's denominator. Add that to the numerator Write that result on top of the denominator. Eample: Convert / to an improper fraction. Multipl the whole number b the denominator: = Add the numerator to that: + = Then write that down above the denominator, like this: Converting Improper Fractions to Mied Fractions To convert an improper fraction to a mied fraction, follow these steps: Divide the numerator b the denominator. Write down the whole number answer Eample: Convert / to a mied fraction. Divide: = with a remainder of Write down the and then write down the remainder () above the denominator (), like this:
