Question

3. Define equivalence relation on a set A. An equivalence relation R
on Z is defined as R = '{(a,b) e Z Z2 divides a - b}. Find
equivalence class of 0 i.e. (0).​

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
