Subtracting a fraction from a whole

Rewrite the whole as a fraction using  5  as the denominator :

            5         5 • 5

    5 =  —  =  —————

            1                5  

Equivalent fraction: The fraction thus generated looks different but has the same value as the whole

the Common denominator: The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

        5 • 5 - (1)                  24

———————————  =  ——
