"как из обычной дроби сделать неправильную?\n"

To make an improper fraction from a proper fraction, simply multiply the whole number by the denominator and add the numerator, keeping the same denominator. For example, if you have the fraction 3/2, multiply 3 by 2 to get 6, then add the numerator to get 6+1=7. Thus, 3/2 can be written as the improper fraction 7/2.
