Okay, what do you need help with?

Answer 2

False, quoting wikipedia:
"In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, with the denominator q not equal to zero. Since q may be equal to 1, every integer is a rational number."

And quoting this website,

" A reciprocal, or multiplicative inverse, is simply one of a pair of numbers that, when multiplied together, equal 1. If you can reduce the number to a fraction, finding the reciprocal is simply a matter of transposing the numerator and the denominator. To find the reciprocal of a whole number, just turn it into a fraction in which the original number is the denominator and the numerator is 1."

you can't multiply whole numbers to get 1 every time. It will always grow (unless you do 1 * 1), it may grow as a negative number, but it will grow.
