Hellppp < 3 ; 3 which number produces a rational number when added to 0.5? a. square root 6 b. pi c. –3.5 d. 0.

Hello,

A rational number is any number that can be expressed as a fraction (using integers).

For answer choice A,  is ≈ 2.949, which cannot be expressed as a fraction.

For answer choice B, Pi is not a rational number, and the sum of any number and pi cannot be rational.

For answer choice C, -3.5 is a rational number, which can be represented by -7/2. When 0.5, or 1/2, is added, we get -3, which can be represented by -6/2. 

So, the answer is C, but we should check answer D just to make sure it does not work.

0.5050050005... is not a rational number that can be represented by a fraction. It is infinite, and when added to 0.5 is 1.050050005, which cannot be represented by a fraction and is therefore not rational.

The answer is C.

Hope this helps!
