The mixed fraction PQ/R = (P*R + Q)/R
There are no alternative refrigerants than can be added on top of/mixed with R-12.
To convert a mixed number to an improper fraction, multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator.
Suppose n/d is an improper fraction where, by definition, n > d.Divide n by d to give a quotient q and a remainder r. Then the equivalent mixed number is q r/d.
To find the reciprocal of a non-zero fraction, simply swap the numerator and the denominator. So R(2/3) = 3/2 : where R() stands for "the reciprocal of" ... whatever is in the brackets. Remember that 12 = 12/1 so R(12) = R(12/1) = 1/12. If you have a mixed fraction then there is one additional step you need to do first and that is to convert it to an improper (or top-heavy) fraction. So R(23/4) = R(11/4) = 4/11
