Question

what is the sum of the rational numbers -8/19 and -4/57 pls answer fast guys please

Answer 1

"The sum of two rational numbers is rational."

So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.

eg:  

4/7 , 32/23 , 34/ 56

The sum of two rational numbers say 4/7 + 3/7 will give 7/7.

Which is equal to 1. The number 1 can be written in p/q form i.e. 1/1 =1

Therefore the sum of any two rational numbers will always result in a rational number.
