Question

Which statement is true about the sum of two rational numbers?

Answer 1

The sum of any two rational numbers is always rational; therefore, we can write the result as a fraction.

For example,

1/2 + 2/3 = 3/6 + 4/6 = 7/6

In more general terms

a/b + c/d = (ad+bc)/(bd)

We cannot divide by zero so neither b nor d can be zero.

Final Answer: Choice A) It can always be written as a fraction
