Answer 1

Answer:

Subtracting a fraction from a whole

Rewrite the whole as a fraction using t2 as the denominator :

t t • t2

t = — = ——————

1 t2

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
