Question

if a b are tow rational numbers, then a+b is a rational number. check the statement talking a, b value

Answer 1

Step-by-step explanation:

Let's take example , a as 1 , -2 as b

then both a and b are rational numbers

so , add a and b

a+b=1 + (-2)

=>a+b=1-2

=> a+b = -1

here -1 is also a rational number therefore sum of two rational numbers (a+b) is also a rational number
