Question

if a and b are two integers then which of the following may not be an integer.
1) a+b
2) a-b
3) a×b
4) a/b
please help...​

Answer 1

Answer:

a/b

Explanation:

Let a be 3 and b be 2

a+b = 3+2 =5 ( integer)

a-b = 3-2 =1 ( integer)

a×b = 3×2 =6 ( integer)

a/b = 3/2 ( rational)

Answer 2

Answer:

4. a/b

Explanation:

as it isnot necessary for a number to be integer after division

for example : a=1, b=2

a+b = 1+2=3

a-b= 1-2=-1

a×b = 1×2=2

a÷b isnot equal to integers
