Question

Is
(a) 1÷a =1 ?
(b) a÷(-1) = -a?
For any integer a.
Take different values of a and check.

Answer 1

both the equations are true for only one integer that is 1

(a) let a=1
lhs → 1÷1 = 1
rhs → 1
lhs = rhs

(b) let a=1
lhs → 1÷(-1)=-1
rhs → -1
lhs = rhs

hence proved

Answer 2

Answer:

Step-by-step explanation:

a)1÷a=1

let a=1

LHS=1÷1=1

RHS= 1

LHS= RHS

b)a÷(-1)=-a

let a=1

LHS=1÷(-1)= -1

RHS= -1

LHS=RHS

Hence proved
