-22 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.

No. It is a rough but rational approximation for the irrational number, pi...Which can expressed as a fraction 22/7.

No, it is rational. A rational number is one which can be expressed as a ratio between two integers. Since 22 and 7 are both integers, then 22 over 7 is rational.

No. An irrational number isn't a whole number, nor can it be represented exactly as a fraction of two whole numbers. 50 is a whole number, so it's rational. 50/3, while having a repeating decimal, is still rational because it's an exact fraction. The square root of two is irrational because there is no fraction that can exactly represent it. The same goes for pi (although 22/7 is close enough for government work -- jk).

No because it is 10 times the square root of 5

No, in fact unless an integer has an integral square root, the square root is always irrational. Note that some rational fractions can have rational square roots, though. Example: sqrt(4/9) = sqrt(4)/sqrt(9) = 2/3, which is rational. Or sqrt(9/16) = 3/4

Any whole number is RATIONAL, since you can write it as a fraction with a denominator 1. In this case, 22/1.

Because it cannot be expressed in the form p/q where p and q are integers (q >0).

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.
