Improper Fraction. Introducing whole fraction

Three types of fractions

Type1.  Proper fraction

, where 2 < 5 (means the numerator is smaller then the denominator)

Type2. Improper fractions

, where 7 > 5(it means that the numerator is higher then the denominator)

Type 3. Mixed fractions

mixed fraction, here we have whole in front of the proper fraction

 

Improper fractions

If we have a improper fraction (numerator is greater than the denominator) then we can get the whole of the fraction. To remove the whole of the fraction procedure:

 

 

If we have the fraction   fraction a/b with  a > b and we get: a : b = c rest r,

 

then:

fraction improper

Example:

 improper fra

because 8 : 3 = 2 rest 2.
