Rewriting the whole as an Equivalent Fraction

6.1 Subtracting a fraction from a whole

Rewrite the whole as a fraction using 10 as the denominator :

22v81 22v81 • 10

22v81 = ————— = ——————————

1 10

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
