# Name the property under multiplication used in each of the following:  Now,

(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

Here, 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

Here, Hence here commutative property is applied.

(iii) Multiplicative Inverse: A rational number c/d is called multiplicative inverse of a/b if Here, Hence the property applied here is multiplicative inverse.
