Name the property under multiplication used in each of the following:
(i) Multiplicative Identity: when we multiply any rational number by 1, we get the number itself.
i.e. if m is any rational number, then we have
1 × m = m × 1 = m
Hence the property applied here is multiplicative identity.
(ii) Commutative property: If m and n are two rational numbers the
Then, m × n = n × m
Hence here commutative property is applied.
(iii) Multiplicative Inverse: A rational number c/d is called multiplicative inverse of a/b if
Hence the property applied here is multiplicative inverse.
