You wont be able to add a rational number and an irrational number and get a number not in a fraction ( 3 + 22/7) (21/7 + 22/7 = 43/7) So, yes as you see in the example above it made another irrational number.

7 plus the square root of 5 is an irrational number because the square root of 5 is a never ending decimal number that can't be expressed as a fraction.
Pi, the numerical value of the ratio of the circumference of a circle to its diameter.

7/3 is a rational number because it's expressed as a fraction
No it is a whole number so it cannot be irrational.
It is: 21/3 = 7
-7 is a rational number
No.
Yes - if I had an irrational number x, and I added that to the number (7-x), I would end up with 7.If the number is irrational, it can be subtracted from a rational/integer to make another irrational.
22/7 is equal to 3 1/7. Note that this is not equal to the irrational number pi, although it is quite close.
