# Q. Is   (i) 1 ÷ a = 1?      (ii) a ÷ (–1) = – a? for any integer a. Take different values of a and check.

(i) $1 \div a = 1$ is true only for $a =1$.

(ii) $a \div (-1) = - a$

Taking, $a =1; 1\div (-1) = -1$

$a =2; 2\div (-1) = -2$

$a =-1; (-1)\div (-1) = 1$

Hence, this is true for every integer .
