Rewriting the whole as an Equivalent Fraction

2.1 Adding a whole to a fraction

Rewrite the whole as a fraction using 7 as the denominator :

11 11 • 7
11 = —— = ——————
1 7
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

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

Adding fractions that have a common denominator :

2.2 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:

p + 11 • 7 p + 77
—————————— = ——————
7 7
